This page sets Compress Image to aim for 500 KB, the most generous image target here. Add one picture and the tool tests JPEG quality levels, returning the best version that stays at or under the limit. It is a sensible choice for large photos that only need to be a bit lighter. Everything runs inside your browser.

Your compressed image(s) will appear here, ready to download.
When you need a file under 500 KB
- A full-resolution photo from a modern phone is several megabytes, and a form or email needs it lighter without looking noticeably worse.
- You want to send a handful of pictures in a single message, and trimming each one keeps the total from growing too big.
- A high-quality scan of a drawing or document must be uploaded, and you want to retain fine lines while meeting a size limit.
- A gallery or blog post needs images that load quickly but still look sharp on a large screen.
What to expect
- At 500 KB the tool has plenty of room, so quality loss is often subtle and hard to spot at normal viewing size.
- Results are always JPEG. A lossless PNG screenshot may change character, with slight halos around crisp text.
- A transparent PNG or WebP is not changed, since flattening it would remove the transparency.
- If your image is already below this size, the tool may find that a re-encode is not smaller and then returns your original.
How to use Compress Image to 500 KB
Add one image. Drop a single image onto the upload area or choose it from your device. Fit to a target size works on one image at a time.
Check the mode. Fit to a target size is already selected. Switch to Compression level for Low, Medium or High.
Check the target. 500 KB (500 KB) is already entered in Target size. Change it if you need a different size.
Fit the image. Select Fit image to size and wait for the progress bar to finish.
Download the result. Compare the sizes and download the JPEG. If the target was missed you are told.
Limits and privacy
- One image at a time in this mode, up to 25 MB.
- Output is always JPEG, so PNG and WebP inputs are re-encoded as JPG.
- An image with real transparency is left untouched, because JPEG cannot store transparency.
- If the target cannot be reached you get the smallest result the tool can make, marked as missing the target.
- The file is processed in your browser and is not uploaded.
- Without an account you get 3 free actions on this tool every 24 hours; signing in removes the cap.
Frequently asked questions
What if my file is still bigger than 500 KB?
It will be reported as missing the target, with the smallest JPEG the tool could produce provided for download. Very large dimensions are the usual reason, and shrinking the picture with Resize Image first normally solves it.
Will the picture look different at 500 KB?
Slightly at most for a typical photo. The search picks the highest quality that fits, so a picture only a little above the limit changes very little.
Does this reduce the pixel size of my photo?
No, only the compression quality is adjusted. Width and height remain as they were.
Can I keep the original format?
Not when compression succeeds, because the output is a JPEG. If the original is kept because nothing smaller was found, it stays in its own format.
