Why convert images to JPG locally

JPG remains the default format for photos on the web because it balances quality and file size. A 1080p photo saved as PNG often measures 2-4 MB while the same image as JPG drops to 150-400 KB. Toolsly runs the conversion inside the browser using WebAssembly so the original file never leaves your computer.

Supported input formats

The converter accepts the formats listed below. Each conversion happens client-side.

• PNG files retain transparency until the export step removes the alpha channel.
• HEIC files from recent iPhones convert without quality loss at 90 percent JPEG quality.
• WebP images from Chrome screenshots shrink further when saved as JPG.

Use the PNG to JPG tool for direct PNG handling or the HEIC to JPG tool when you receive iOS photos.

Format comparison table

Format	Compression	Transparency	Browser support	Typical use case	Average size for a 1080p photo
PNG	Lossless	Yes	All	Graphics	2-4 MB
JPG	Lossy	No	All	Photos	150-400 KB
WebP	Lossy/Lossless	Optional	Modern	Web images	80-250 KB
HEIC	Lossy	Yes	Limited	iPhone photos	500 KB-1.5 MB
AVIF	Lossy	Yes	Growing	Next-gen web	50-150 KB
BMP	None	No	All	Legacy systems	3-6 MB

Step-by-step conversion process

Open the main converter page and drop your file onto the drop zone. The browser reads the file into memory, decodes it with the appropriate codec, then re-encodes it as JPEG at the chosen quality level between 60 and 95. A 12-megapixel HEIC file typically finishes in under three seconds on a mid-range laptop.

After conversion the new JPG downloads automatically. No temporary files remain on disk.

Adjusting quality settings

Lower quality values reduce size quickly. At 80 percent quality most viewers notice no difference on a standard monitor. Test a sample first if you plan to print the result later.

Privacy considerations for sensitive images

Photos often contain location data or personal details. Because the category/image tools process everything locally, EXIF metadata stays private unless you explicitly choose to strip it during export.

Related workflows

After converting to JPG you may want to reduce dimensions further with the Image Resize tool or remove unwanted areas using the Image Cropper. If you need to archive multiple converted files, the Images to PDF tool creates a single document without leaving the browser.

Common file-size outcomes

• A 3.2 MB PNG screenshot becomes 240 KB at 85 percent quality.
• A 1.8 MB HEIC from an iPhone 14 converts to 310 KB JPG.
• A 420 KB WebP marketing graphic ends at 180 KB JPG.

These numbers vary with image content and chosen quality but remain consistent across the local pipeline.

Limitations to keep in mind

Animated images lose motion when saved as static JPG. Vector files such as SVG require rasterization first and may need the separate category/image tools for best results. CMYK images from print workflows convert to RGB JPG only.

The converter does not support batch processing of more than 20 files in a single session to avoid memory spikes.

When to choose another format instead

If transparency matters, keep the file as PNG or WebP. For maximum compression on modern browsers consider AVIF through external software. JPG excels when broad compatibility and small file sizes are the priority.
