Compress an Image to 50KB
50KB is a realistic target for most photos without an obvious quality drop. CurePDF binary-searches the quality setting for the best result that fits, and reports the size it actually reached.

How to Compress an Image to 50 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>Photographs compress well at this size. Screenshots and graphics with text do not — sharp edges and flat colour are exactly what JPEG handles worst, so text can look fringed. For those, try a smaller pixel size rather than lower quality.</p><p>If an image is already under 50KB, CurePDF leaves it alone rather than re-encoding it and making it worse for no benefit.</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.
