Just Upload

Fix rejected uploads as you upload. Converts, compresses, resizes and crops files to fit each website's rules, on your device.

Fix rejected uploads before they happen. Just Upload reads a website’s file requirements and automatically prepares a compatible copy before uploading. If your file already works, it does nothing. WHAT IT CAN FIX • Convert image formats like HEIC, WebP, AVIF, TIFF, GIF and more • Compress files that exceed size limits • Resize images to required dimensions • Prepare passport and exam photos • Convert images ↔ PDF • Compress PDFs • Convert Excel ↔ CSV • Create ICO favicons • Handle large scans and images up to 5 GB Just Upload asks before changes like cropping, enlarging, removing transparency, selecting PDF pages or Excel sheets, or significantly reducing quality. If a website doesn’t clearly state its requirements, use “Fix a file yourself” and enter a rule like: “JPG, under 500 KB” PRIVATE BY DESIGN • Everything runs on your device • No servers • No accounts • No tracking or analytics • Works offline • Originals are never changed No settings to learn. Just choose your file and upload.
