Browse the whole catalog by category
Ten categories, 360+ tools — jump straight to the shelf you need.
Toolsly is organized the way a good toolbox is: everything has a drawer. Instead of bookmarking a dozen single-purpose sites — one for images, another for PDFs, a third for that one calculator — you open one hub and pick the category. Each category below is a complete shelf, not a teaser: the image drawer alone covers PNG, JPG, WebP, AVIF, HEIC, GIF, BMP, SVG and TIFF in every sensible direction, plus resize, compress, crop and rotate. The document drawer converts between Markdown, PDF, DOCX, HTML, CSV, JSON, YAML and Excel. Audio and video transcode the formats people actually have, and pull audio or GIFs out of clips. Text and dev cover the encode-decode-format-validate loop. Color handles hex, RGB, HSL, palettes and WCAG contrast. Calculators answer the everyday questions — percentages, loans, dates, BMI. And the payment shelf carries the card-industry niche almost nobody else hosts: Luhn checks, BIN lookups, EMV TLV decoding, and the ISO 4217 / 3166 / MCC code tables you keep forgetting. Pick a drawer and the full grid for that category opens.

The tools people open first
Eight of the most-used utilities in the catalog — a fast way to see what Toolsly does.
Not sure where to start? These eight are the requests that come up most across the whole catalog, deliberately chosen to span it: an image converter, an image optimizer, a media extractor, a code formatter, a generator, a color utility, an everyday calculator and a PDF tool. They are a representative slice rather than a top-ten list — open any one and you get an honest sense of how the other 350-odd behave. The pattern is identical everywhere: drop a file or paste text, see the result render in seconds, copy or download it. There is no settings wizard to learn first and no demo gate to clear. The image, text, color and calculator tools below do their work inside the page itself, so a conversion finishes at the speed of your own machine rather than a round trip to a queue. Treat this row as a sampler: find the one closest to today's task, and let the search box handle tomorrow's.
PNG to JPG
The single most-requested image conversion in the catalog. It flattens transparency onto a solid background and re-encodes as JPEG, which typically cuts a screenshot or export to a fraction of its original size. Ideal when a form, email or upload field rejects PNGs or chokes on large files.
Open tool →Compress image
Shrinks the file size of a JPG, PNG or WebP for the web, email or a slide deck while holding visible quality steady. You nudge a quality slider and watch the projected size update before you commit. It is the fastest way to get a heavy photo under an attachment or page-weight limit.
Open tool →MP4 to MP3
Pulls the audio track out of a video and saves it as a standalone MP3 — handy for lectures, interviews, podcasts and music captured as video. You can keep the full length or trim to the part you actually want. The output is a clean, portable file that plays anywhere.
Open tool →JSON formatter
Pretty-prints messy or minified JSON into clean, indented, readable structure and flags syntax errors with the line that broke. Paste an API response or config blob, get back something you can actually scan and copy. It is the dev tool that quietly gets opened a dozen times a day.
Open tool →QR code generator
Turns a URL, Wi-Fi login, vCard contact or block of plain text into a crisp, scannable QR code. Download it as a high-resolution image and drop it onto a flyer, slide, menu or business card. No tracking redirect sits between the code and its destination.
Open tool →Color converter
Translates any color between hex, RGB and HSL the moment you type it, so a value from a design file drops straight into your CSS. It is the quickest way to settle the format mismatch between a brand guide and a stylesheet. Pair it with the palette and contrast tools in the same category.
Open tool →Percentage calculator
Answers the everyday percentage questions in one box — what percent of X is Y, an increase or decrease, a tip or a discount. You skip the mental arithmetic and the spreadsheet, and read the result instantly. It is the calculator people reach for mid-task without breaking stride.
Open tool →PDF merge
Combines several PDFs into one ordered document, with drag-to-reorder before you export. Stitch a contract, an appendix and a cover page into a single file ready to send. It pairs with the split tool on the document shelf for the reverse job.
Open tool →Why a hub beats a scatter of single-purpose sites
What you get from one catalog you don't get from ten separate tabs.
The single-purpose tool site is a familiar trap. It does its one job well, then leaves you back on a search engine hunting for the next format, the next converter, the next calculator — and each result is a different domain with its own layout, its own ad wall and its own idea of what counts as free. Toolsly collapses that scavenger hunt into one address. The table below lines up the differences that actually decide where your afternoon goes: how much ground a place covers, what happens to your files, what it costs in money and friction, and how long it takes to find the right tool in the first place. The pattern is consistent across all 360+ tools, which is the real advantage — once you know how one works, you know how they all work. Coverage and consistency are the things a scatter of bookmarks can never give you, no matter how good each individual site is.
| What matters | One scattered single-purpose site | Toolsly (the whole catalog) |
|---|---|---|
| Coverage | One task — re-hunt for the next one | 360+ tools across 10 categories in one search |
| Where files go | Often uploaded to someone's server | Client-side tools run in your browser; files stay put |
| Cost & friction | Sign-ups, watermarks or paywalls common | Free, no account, no watermark, no limits |
| Finding the tool | Bookmark sprawl across many domains | One search box and a category filter |
| Consistency | A new layout and quirks every time | One interface, same drop-paste-download flow everywhere |
Whatever you came to do, there's a drawer for it
A catalog this broad serves very different people on the same afternoon.
Breadth is not a vanity metric here — it is what lets one tab serve a student, a designer and a developer on the same afternoon without any of them noticing the others. The four profiles below are not marketing personas; they map to the clusters of tools people actually chain together. A writer turning notes into a submission touches the document and calculator shelves. A designer prepping assets lives in the image and color drawers. A developer mid-feature bounces between text, dev and diagram tools. And almost everyone, eventually, has one of those small odd jobs — a QR code, a PDF split, an audio rip — that used to mean opening a fresh stranger's website. Because the interface and the drop-paste-download rhythm are identical across every category, switching between these roles costs nothing. You don't learn Toolsly four times; you learn it once and the rest follows.
Students & writers
Turn Markdown notes into a polished PDF, merge several research documents into one file, and drop image sizes so an assignment slides under an upload limit. Work out a percentage or a date difference in the same tab, with nothing to install and no account to create.
Designers & creators
Convert HEIC photos straight off a phone into shareable JPGs, then compress assets so a page or email stays light. Translate colors between hex, RGB and HSL to match a brand guide, and build a palette without leaving the browser.
Developers & data folks
Format and validate JSON, decode a JWT, hash a string and spin up UUIDs without breaking flow. Render a Mermaid diagram to SVG and minify your markup — the whole mid-task utility loop sits in one tab instead of five.
Anyone with a quick task
Pull the audio out of a video, generate a scannable QR code, split a long PDF down to the pages you need, or work out a loan payment. These are the small one-off jobs you'd otherwise scatter across a dozen unfamiliar sites.
Guides for getting it right
How-to walkthroughs across every category — format explainers, conversion tips and the difference between tools that look alike.
The catalog gets you the result; the guides explain the choices behind it. Across the blog we cover the practical questions that come up while you work — when to reach for JPG over PNG, why HEIC files need converting before you can share them, what WebP and AVIF actually save you, how lossless and lossy compression differ, and where everyday calculators trip people up. Because Toolsly spans all ten categories, the guides do too: image-format explainers, document-conversion walkthroughs, audio and video basics, and quick references for the color and payment-code utilities.

Read guide →How Toolsly works
Three steps, the same everywhere in the catalog.
There is one flow to learn, and it never changes from tool to tool. That is deliberate: a directory only earns the name if the four-hundredth tool feels as obvious as the first, so every page in the catalog follows the same three beats — find it, feed it, fetch the result. There are no per-tool tutorials to read and no settings panel standing between you and the output. The steps below describe the entire experience, whether you are flattening a PNG, merging a contract or decoding an EMV tag. The only thing that varies is what you hand the tool: a file for the converters, pasted text for the encoders and formatters, or a few numbers for the calculators. Learn the rhythm once on whichever tool you opened today, and every other shelf in the catalog already makes sense before you arrive.

PNG to JPGFrequently asked
What is Toolsly?
Toolsly is a free online hub of 360+ tools across 10 categories — images, documents, audio, video, text and encoding, diagrams, color, dev utilities, everyday calculators and payment-card data. Instead of hunting across a dozen single-purpose sites, you search one catalog, open a tool, and get your result. There's no sign-up, no watermark and no usage limit.
How do I find the right tool quickly?
Use the search box at the top of the homepage to type a format or task (like 'heic to jpg' or 'merge pdf'), or pick one of the 10 category filters under it to browse that shelf. Every tool is one click from the homepage, and the popular tools are listed near the bottom if you just want the most-used ones.
Are my files uploaded to a server?
For the client-side tools — which include most image, text, color and calculator utilities — the work happens entirely in your browser, so the file never leaves your device. A few heavier conversions (some audio and video transcodes) run on a server because browsers can't do them efficiently; those are the exceptions, and each tool page makes clear where it runs.
Is Toolsly really free, and do I need an account?
Yes, it's free with no account required. There are no sign-ups, no watermarks on output, and no usage caps — open a tab, use as many tools as you like, and close it. Toolsly is built to be the toolbox you reach for without thinking about pricing tiers.
Which categories and formats does Toolsly cover?
All ten: image (PNG, JPG, WebP, AVIF, HEIC, GIF, BMP, SVG, TIFF), document (Markdown, PDF, DOCX, HTML, CSV, JSON, YAML, Excel), audio (MP3, WAV, OGG, FLAC, AAC, M4A, OPUS), video (MP4, MKV, WEBM, MOV, AVI), text and encoding, Mermaid diagrams, color, dev formatters, everyday calculators, and payment-card utilities. That breadth is the point — it's a mega-directory, not a single-purpose converter.
How is Toolsly different from a single-purpose converter site?
A single-purpose site solves one task, then you re-hunt for the next. Toolsly keeps 360+ tools behind one search box with a consistent drop-paste-download flow, so your whole list of little jobs — convert an image, pull audio from a video, format some JSON, make a QR code — gets done in one tab instead of ten.
Does Toolsly work on mobile and any browser?
Yes. Everything runs in a modern web browser with nothing to install, so it works on desktop, laptop, tablet and phone. The client-side tools use standard browser capabilities, and the interface is the same across the catalog, so a tool you learn on desktop behaves identically on your phone.
What are the payment and card tools for?
They're a niche shelf most general tool sites skip: Luhn validity checks, BIN lookups, EMV TLV tag decoding, PIN block and KCV helpers, and lookup tables for ISO 4217 currency codes, ISO 3166 country codes and MCC merchant categories. They're aimed at developers and payments professionals who work with card data and need a quick, in-browser reference or decoder.
