Preset to 50 KB

Compress JPEG, PNG, or WebP images to 50 KB in your browser

Add up to 20 images by drag and drop, file picker, or paste. Processing starts as soon as the files are read. Keep the original format or switch to JPEG or WebP for smaller photos, then download each result or all of them as a ZIP.

When 50 KB is the right target

What a 50 KB image is good for

A 50 KB limit suits thumbnails, product grid images, and messaging app attachments. It is small previews that must load instantly on slow mobile networks. At this size a photograph usually needs smaller pixel dimensions as well as a lower quality setting, so the compressor reduces dimensions when quality alone cannot reach the target.

How the target search works. The compressor encodes the image at decreasing quality levels until the output is under 50 KB, keeping the highest quality that fits. If even the lowest quality is still too large, it scales the dimensions down and tries again, and it tells you when a target was not reached rather than silently returning a bigger file.

Need a different size?

Every target from 20 KB to 1 MB and a custom kilobyte value are available on the full compressor.

Questions about 50 KB images

Compress to 50 KB FAQ

How do I compress an image to 50 KB?

Drop the image on this page: the compressor is preset to a 50 KB target and starts immediately. It searches for the highest quality that still fits under 50 KB, then shows the real encoded size so you can download the result or adjust the format.

Will compressing to 50 KB make my image blurry?

At 50 KB a large photo usually needs both a lower quality setting and smaller dimensions, so fine detail and text can soften. Use JPEG or WebP for photos, and reduce the pixel dimensions first when the picture will be displayed small anyway.

Which format reaches 50 KB most easily: JPEG, PNG, or WebP?

WebP and JPEG compress photographs far more efficiently than PNG. PNG stays lossless, so it only gets smaller through fewer pixels or colours; choose it when you need transparency or crisp screenshots. The tool reports whether the 50 KB target was actually reached for each file.

Is my image uploaded to compress it?

No. Decoding, resizing, and re-encoding all happen in your browser tab with the browser's own image encoder. The file never leaves your device, and there is no account or file limit beyond the 25 MB per-file and 20-file batch caps.
