Compress an image to 500 KB
500 KB is where “compression” stops meaning “compromise”: nearly any photograph at web or document dimensions fits with no visible loss. The typical visitor here has a folder of 4–8 MB camera files and a system that politely refuses anything over half a megabyte.
Drop the folder’s worth of files below — batch is supported — and each is re-encoded on your device to just under 500 KB.
Drop images here — or click to browse, or paste with Ctrl+V
JPG · PNG · WebP — processed on your device, never uploaded
How it works
- Open this page — the compressor is already set for “Compress image to 500 KB”.
- Drop your image into the box, click to browse, or paste it with Ctrl+V.
- The tool re-encodes the image on your own device until it fits the target — nothing is uploaded.
- Check the preview and file size on the result card, then download.
Quality at 500 KB
Up to ~2500 px on the long side: expect visually lossless results for almost all content.
Even full-resolution DSLR frames often fit at high quality; when they don’t, the automatic dimension step-down is gentle and usually invisible for screen use.
Getting the dimensions right
If these photos are heading to a website, consider WebP output at 500 KB — at this budget WebP delivers effectively perfect quality at dimensions JPEG can’t match.
Frequently asked questions
Why are my camera’s JPEGs 6 MB if 500 KB looks the same?
Cameras encode at maximum quality with full sensor resolution so you can crop and edit later. For sharing and uploading, most of those bytes carry detail no screen will ever display — recompression harvests them.
Is there a limit on how many photos I can batch?
No hard limit — they’re processed sequentially on your machine, so the practical limit is your patience. Hundreds of files work; the tab just takes a while.
What about my photo library’s originals?
Keep them! Compress copies for upload and sharing; the originals on your device or backup are your archive. This tool never modifies the source file — it always produces a new one.
