Each page is rendered to a JPEG and reassembled into a new PDF, typically dropping file size by 3-10x for scan-heavy or image-heavy documents. IMPORTANT: this is a lossy process — selectable text and vector graphics in the original PDF become flat images, so the output PDF is no longer searchable or copy-pastable. Use this when size matters more than text fidelity (e.g. emailing scans). Everything runs locally in your browser.","category":"document","categoryName":"Document","keywords":["compress pdf","compress pdf online","compress pdf free","shrink pdf","reduce pdf size","pdf compressor","make pdf smaller","optimize pdf size","pdf size reducer","compress pdf in browser","downsize pdf","compress scanned pdf"],"url":"https://toolsly.tools/pdf-compress","runsOn":"client","multiple":false,"batch":false,"input":{"type":"file","extensions":[".pdf"],"mimeTypes":["application/pdf"]},"output":{"type":"file","extension":".pdf","mimeType":"application/pdf"},"options":[{"type":"select","key":"quality","label":"Quality","defaultValue":"medium","choices":[{"value":"high","label":"High (150 DPI)"},{"value":"medium","label":"Medium (96 DPI)"},{"value":"low","label":"Low (72 DPI)"}],"help":"Output PDF is rasterized — selectable text in the original becomes a flat image."}],"invocation":{"webUi":"https://toolsly.tools/pdf-compress","api":null,"notes":"Currently runs client-side in the user's browser.
