When 200 KB is the limit
A 200 KB limit gives room for detail. It is common for uploads of certificates, mark sheets, experience letters and other single-page documents, for a full-length or group photograph, and for portals and email systems that cap each attachment. Since the limit is generous, the aim on this page is different from the smaller sizes: keep as much of the original as possible and change only what is needed to get under 200 KB.
Keep the pixel size where possible
Up to a few megapixels, most photos and document scans fit in 200 KB just by lowering the JPG quality a little, so the width and height stay as they were. That matters for documents that may be zoomed or printed by whoever receives them. Only larger pictures, such as a 12 megapixel phone photo, also need fewer pixels; the page then shrinks them in small steps and raises the quality again as far as the limit allows. The result always shows the final width and height, so there are no surprises.
Shrink photos under 200 KB for sharing
200 KB is also a good everyday size for sending photos where data is limited or a site rejects large files. A photo around 1,600 pixels wide at 200 KB looks good on any phone or laptop screen and loads quickly. Choose a set of photos together and each one comes out under 200 KB, ready to save one by one or with Download all.
JPG, PNG or WebP?
- JPG (the default) suits photos and scanned documents and is accepted everywhere.
- PNG suits screenshots, diagrams and logos with flat colours. It has no quality setting, so the page reaches 200 KB by reducing the width and height.
- WebP gives smaller files for the same look, but some upload forms do not accept it. Use it only when you know it is allowed. Not every browser can save WebP, Safari in particular; the page tells you if that happens.
Multi-page documents
This tool works on images, one picture per page. A document of several pages is best uploaded as a PDF if the form allows it; if it needs images, photograph or export each page and compress them together here.
Smaller limits
For tighter limits use compress image to 100 KB, which explains how to keep text readable, or compress image to 50 KB for photographs. Reduce image size in KB takes any number. Every image tool runs in your browser, so documents never leave your device.
The image is redrawn with your browser's own canvas, so the result depends on the browser's JPG, PNG and WebP encoders. MDN's image file type guide explains which format suits photos, signatures and scans.
