Compress Image to Exact KB (20KB, 50KB, 100KB)
Compress or resize a photo to an exact size — anywhere from 10KB to 2MB — the general tool behind every specific KB-target page on this site. Type any target and the tool steps quality down until the file lands strictly under it.
What it does
- Type any exact KB target, not just the common presets.
- Quality-first compression keeps faces sharper than dimension-shrinking alone.
- Batch multiple photos to the same target at once.
Private by design
Processing runs entirely inside your browser tab — your photo or document is never uploaded to a server.
Good to know
There's no sign-up, no email, and no limit on how many times you use it in a day — it's free the same way every time.
How it works
Frequently asked questions
How is this different from the specific '100KB', '50KB' pages?
Same engine — those pages simply pre-fill this target for one click; use this page directly for any other number, like 73KB.
Will the output always be strictly under my target, not just close?
Yes, the tool checks the actual encoded size after each pass and keeps compressing until it's under the target.
