Image Converter & Compressor: PNG, JPG, WebP

Shrink photos under 100 KB for forms, or convert PNG, JPG and WebP. Free, offline, and nothing is ever uploaded.

Shrink a photo under a size limit such as 100 KB, or convert images between PNG, JPG and WebP, without uploading anything. Everything runs inside your browser, so ID photos, signatures and documents stay on your device. HOW IT WORKS Right-click any picture on a web page and choose "Save image as…", or open the extension and drop files in. Pick Convert for a new format, or Shrink to size for a limit. SHRINK TO A FILE SIZE Online forms often reject photos over a set size. Tap 20, 50, 100, 200 or 500 KB (or 1 MB), or type your own limit, and the extension finds the highest quality that fits. It reduces the dimensions only when it has to. • At or under your limit whenever it can be reached, counting 1 KB as 1,000 bytes • Keep dimensions, for forms that need an exact pixel size • If a limit is too tight, you get the closest result and a clear reason • With Same format selected, a file already under your limit is left as it is CONVERT BETWEEN FORMATS • One right-click saves a web picture in a new format • Drag in, paste (Ctrl+V) or choose many files at once • Reads AVIF, GIF and BMP too • Transparent areas get a fill colour you choose, with a warning SEE WHAT CHANGED Every file shows its before and after size, the percentage saved, the new dimensions and the quality used. Copy a PNG result to the clipboard, download everything at once, or open the converter in a tab to keep your work while you browse. PRIVATE BY DESIGN • Files are processed on your device with your browser's own engine • No account, no tracking, no analytics, no watermark • Converted files carry no camera or location (EXIF) data • Works offline QUESTIONS How do I get a photo under 100 KB? Choose Shrink to size, tap 100 KB and drop the photo in. Download the result. Is anything uploaded? No. When you right-click a picture, the extension requests it from the site that hosts it, the same address your browser already loaded, then processes it locally. Nothing is sent to us. Why does my PNG not get smaller? PNG is lossless, so its quality cannot be lowered. Choose JPG output, or turn off Keep dimensions so it can be resized. Does it keep transparency? PNG and WebP do. JPG cannot, so you choose the fill colour. Is it free? Yes, with no cap on how much you use it. PERMISSIONS Right-click menu, saving files, remembering your settings, and a message if a picture cannot be processed. Access to all sites is optional and requested only if a website blocks direct access to its picture. More free image and PDF tools: https://smallprep.com/tools
