Compress Image to 500 KB
Compress images to 500 KB or less in your browser — no signup, no limits, nothing uploaded to any server.
No account · No daily limit · No card · Nothing to cancel
Full pixel size keptRe-encodes only if the file gets smaller Nothing is ever made bigger
The encoder works at a quality that does not show, and stops there. You do not pick a number.Your images are processed by your own browser. Nothing is uploaded, there is no account, and there is no daily limit.
Compress to another size
Every limit is different. These run on the same engine, so switching is instant.
At 500 KB you are hardly squeezing anything
At 500 KB you are mostly trimming rather than squeezing. A large photo straight from a modern phone can be 4 MB or more, and 500 KB keeps it looking excellent while cutting it down to a fraction of the size.
If your image is already under 500 KB, the tool leaves it untouched rather than re-encoding it and losing quality for no reason.
Generous caps, and when you meet them
- Portfolio and gallery images that must still look sharp
- Product photography for listings
- Print-at-home photos where you want to keep detail
- Preparing a set of images for a site where 200 KB looked slightly flat
Why a limit would sit this high
A ceiling of several hundred kilobytes is a courtesy limit, not a constraint. Print services, estate agents and camera-friendly platforms set it to stop someone uploading a 40 MB file over a phone connection, while still accepting a photograph with enough detail to work with. Files in this range are usually re-encoded once at high quality rather than compressed in any meaningful sense, and the metadata a camera writes into them — lens, location, timestamps, an embedded preview — is a large part of what disappears.
The result at 500 KB
Excellent. At 500 KB the difference from the original is very hard to see even side by side.
Expect the result to be visually indistinguishable from your original. If your file is already under 500 KB, the tool hands it straight back rather than re-encoding it and losing quality for nothing.
How it works
- Add your imageDrop it above, or choose a file from your device.
- Choose howSmallest file keeps the best quality and takes no number, or set the exact size your form asks for. Nothing is compressed until you press Compress.
- Compress and downloadPress Compress, and the finished size is shown before you save, so there are no surprises.
Questions
How do I compress an image to 500 KB?
Drop your image into the box above, check that the target reads 500 KB, and press Compress. The finished size is shown before you download, so you can see that it fits before you save it.
Is 500 KB going to noticeably degrade my photo?
No. At this size you are inside the range where a single high-quality re-encode is invisible at normal viewing size, and much of what you save is camera metadata rather than picture detail.
Why compress at all if the limit is this generous?
Because the limit is still a limit. A modern phone photo can exceed 500 KB easily, and platforms that state a maximum reject anything above it rather than shrinking it for you.
Will compressing to 500 KB ruin the quality?
Excellent. At 500 KB the difference from the original is very hard to see even side by side.
What can I do with a 500 KB image?
Almost anything short of large-format printing: view it full screen, email it, add it to a document, post it anywhere. At half a megabyte the compression is barely perceptible on screen.
Which format should I choose — JPG, PNG or WebP?
Photos: JPG or WebP, because they are built for photographs. Logos, signatures, screenshots and anything with flat colour: PNG, so the sharp edges stay sharp. If you are not sure, leave it on “keep original format”.
What does “500 KB or less” mean here?
The tool aims just below your number, never above it. If the image is already smaller than 500 KB it is left untouched rather than re-encoded and degraded.
Is this free? What is the catch?
There isn’t one. The compression runs inside your browser using technology already built in, so there is no server doing the work and nothing to charge for. This page shows ads, and that is the whole business model.
