JPG · PNG · WEBP · HEIC — files never leave your browser
300×300 is a common avatar/thumbnail size for forums, eBay listings, employee directories and many older school portals. Drop a photo, square-crop it, and export — entirely in your browser.
What 300×300 is for
300×300 is a classic small-square avatar size: many older forums, legacy ticketing systems and some HR portals still cap profile photos at this resolution. It also matches Gravatar's default size.
How the resize works
The editor crops your source to a 1:1 (square) aspect ratio, then resamples the cropped pixels down (or up) to exactly 300×300. Browsers use a high-quality bilinear / Lanczos filter for the resampling step, so detail is preserved as well as it would be in a desktop image editor. Exact integer pixels — no fractional dimensions, no surprise rounding when an upload portal validates your file.
Picking the right format
- JPG — smallest file, best for photographs and most uploads.
- PNG — lossless, supports transparency, larger file. Pick it when the result will be edited again or layered onto another background.
- WebP — modern, smaller than JPG at the same quality. Universally supported in browsers, occasionally rejected by older desktop apps.

Privacy
Every step happens inside the browser tab you have open. Your image is decoded, cropped and re-encoded by the same JavaScript engine that runs this page — there is no upload, no temporary file on a server, and no "processed copy" cached by us afterwards. When you close the tab, the blob is gone. We document the full pipeline on our Methodology and How it works pages.
FAQ
What's 300×300 good for?
Will it stretch the photo?
Will my photo look stretched?
No. The crop frame is locked to 1:1 (square), so the editor center-crops before resizing. Aspect ratio is preserved.
Can I upscale a small photo to 300×300?
You can, but a meaningful upscale needs more pixels than the source has. Browsers only interpolate — they cannot invent detail. For a sharp result, start from a source at least as wide and tall as the target.
What happens to my image after I close the tab?
It is freed from your browser's memory like any other image you opened. We never received it, so we have nothing to delete on our side. See Trust & Safety for the full policy.
