A target you will hit, so we optimise for quality instead

Because 200KB is comfortably reachable for even a large photograph, the search stops at the first quality setting that fits rather than continuing downward. A photo that could have fit at 190KB is not pushed to 120KB just because it could be. Files already under 200KB are left alone entirely — re-encoding them would only lose quality for no gain in size.

This is the opposite of the 20KB page. There the constraint is what is physically possible; here the constraint is not wasting quality you did not have to spend.

What 200KB is normally for

  • Email attachments, where several photos need to fit under a mailbox limit without looking degraded.
  • Marketplace and classified listings that cap uploads but display images large.
  • Full-width web images and hero banners where quality matters more than the last few kilobytes.

Compress Image to 200KB

My file is already under 200KB. What happens?
Nothing is changed. Re-encoding a file that already fits would only cost quality without saving space, so we return it as it is and say so in the result.
Can I go lower than 200KB here?
Yes, type any number into the target field. If you are consistently aiming lower, the 100KB and 50KB pages explain what changes at those targets.
Are my files kept?
No. Everything is deleted from the server one hour after upload, automatically. There is no account, no sign-up and no watermark.

When 200KB is the right target

200KB is the limit you meet when the system on the other end cares about bandwidth but not desperately. Marketplaces, mail servers and content management systems land here often. It is roomy enough that a detailed photograph keeps its texture, which is not true at 50KB.

If nothing is forcing a number on you and the image is going on a web page, 200KB is a defensible budget for a large photograph and 100KB is better for everything else. If the image is going into an email, 200KB each lets you attach several without hitting a mailbox limit.

How the target is reached

We do not resize your image and we do not convert it to a different format. The target is reached by binary-searching the encoder quality: we encode, measure, adjust and encode again until the result lands just under your number. Because this runs server-side with the real encoders (pngquant, cwebp, gifsicle, libjpeg) rather than a browser canvas, it keeps searching further down than an in-browser tool can before giving up. Target mode is available for JPG, PNG, WebP, GIF, HEIC, JXL, JP2 and JXR; other formats fall back to standard quality-based compression.
