Is 500KB good for website images?

Treat it as an upper bound — fine for a large hero or gallery image. For regular in-page images aim for 100–200KB, or use WebP, to keep pages fast.

Can I save as WebP instead of JPG?

Yes. WebP usually reaches the same size at higher visual quality, and every modern browser supports it. Use JPG if the upload form doesn't accept WebP.

Is the Compress Image to 500KB free to use?

Yes. Compress Image to 500KB is completely free with no sign-up, no watermarks and no usage limits.

Are my files uploaded to a server?

No. Compress Image to 500KB runs entirely in your browser — your files and data never leave your device.

Does it work on mobile and offline?

Yes. It works in any modern browser on desktop or mobile, and the toolkit is a PWA that keeps working offline after your first visit.

Compress Image to 500KB

Shrink large phone and camera photos to under 500KB with minimal visible loss — for website uploads, listings, CMS limits and email. Processed in your browser, never uploaded.

How it works

1
Add your photo
Drop a JPG, PNG or WebP — one or many. It's read in your browser; nothing is uploaded.
2
Set the target size
Type the maximum in KB or MB, or tap a preset like 20KB, 50KB or 100KB. Add a minimum if the form has one.
3
Let it fit automatically
The tool finds the highest JPG quality that fits, and shrinks the dimensions only when quality alone isn't enough.
4
Check and download
Each result shows its exact size in KB and bytes, so you know it will pass the upload check.

Common uses

Upload photos to a CMS, blog or website builder that rejects files over 500KB.
Attach several phone photos to one email without hitting the size cap.
Prepare listing photos for property or classifieds sites with per-photo limits.

500KB is generous: phone and camera photos can usually keep 1600–2000 pixels on the long side, which still looks crisp on a laptop screen. The tool trims megabytes off a straight-from-camera photo by lowering quality only as far as needed.

Compress Image to 500KB is part of a free, privacy-first toolkit. Everything is processed locally on a Canvas with high-quality pica resampling — there are no uploads, no quality loss from a server round-trip, and no limits.
