Free Image & PDF Tools — All in Your Browser
DocuSizer gives you 80+ tools to compress, resize, convert, and edit images and PDFs without uploading a single file. Everything runs locally on your device.
Compress Images to Any Size
Reduce JPG, PNG, and WEBP image file sizes to exact KB targets — 20 KB, 50 KB, 100 KB, 200 KB, or any custom value. Ideal for government exam portals (SSC, UPSC, IBPS, NEET), passport uploads, and college admission forms.
Resize Images in Any Unit
Resize photos to exact dimensions in pixels, centimetres, millimetres, or inches. Includes presets for WhatsApp DP (400×400), Instagram (1080×1080), A4 print, US passport (2×2 inch), and UPSC (200×230 px).
Convert Between Image Formats
Convert JPG to PNG, PNG to JPG, WEBP to JPG, HEIC to JPG, and more — all in your browser. iPhone HEIC photos are supported without installing any software.
Create Passport Size Photos
Generate passport-size photos for India (35×45 mm), USA (2×2 inch), UK, Pakistan, and more. Change the background colour and download a print-ready A4 sheet.
Compress & Convert PDFs
Compress PDF files to 50 KB, 100 KB, 200 KB, or 500 KB. Convert images to PDF, or convert every page of a PDF to a JPG image — all without uploading to any server.
100% Private — No Upload Required
Every tool on DocuSizer runs entirely in your browser using Canvas and WebAssembly APIs. Your images and documents are never sent to any server. Processing works offline after the page loads.
