Compress an Image to 20KB
20KB is a small target, so expect the image to be resized as well as recompressed. CurePDF searches for the highest quality that still fits, and tells you the real size it achieved rather than assuming it hit the target.
Compress Your Image Now
Choose your image and CurePDF compresses it right in your browser — free, no sign-up, no upload needed for most images.
Compress Image to 20 KB →<p>20KB is one of the tightest limits application forms ask for, and it is small enough that quality alone will not get you there. A typical phone photo is 2–5MB, so reaching 20KB means roughly a hundred-fold reduction.</p><p>CurePDF handles that in two stages: it first lowers JPEG quality as far as is reasonable, and only then reduces the pixel dimensions, because shrinking the image is the more noticeable change of the two. Everything happens in your browser, and for most images nothing is uploaded at all.</p>
How to Compress an Image to 20 KB
- Open the Compress Image tool — the target size is filled in for you.
- Choose your JPG, PNG or WebP file.
- Click Compress. The work happens in your browser; no upload is needed for most images.
- Check the reported output size, then download the result.
Things to Keep in Mind
<p>At 20KB, resolution is the limiting factor. A passport-style headshot at 600×600 can look perfectly acceptable; a wide landscape photo at the same file size cannot, because the same bytes are spread over far more pixels.</p><p>If the result looks too soft, crop the image to just the part that matters before compressing. Fewer pixels to describe means more detail retained in the ones that are left.</p>
Frequently Asked Questions
Is my image uploaded to your servers?
No. Compression runs in your browser using its built-in image support, so the file never leaves your device. If your browser cannot handle a particularly large image, CurePDF will say so and offer to process it on our servers — but only if you explicitly agree.
What if the exact target size cannot be reached?
CurePDF tells you the size it actually achieved instead of claiming it hit the target. It stops before quality becomes unusable rather than shrinking indefinitely, so a result slightly over the target is a deliberate choice, not a failure.
Which formats can I compress?
JPG, PNG, WebP, BMP, GIF and TIFF. Output is JPEG or WebP, since those are the formats with a quality setting to trade against file size.
