Compress JPEG to 80KB Online
Drop your JPEG — it lands at 80KB automatically, ready for upload.
100% in your browser — files never uploaded
Why 80KB is a common upload limit
An 80KB ceiling shows up across resume attachments, document scans, and application-form photo fields. This page opens directly in Target Size mode with 80KB pre-filled, so there's no slider to guess with — drop your JPEG and download.
How the 80KB target is reached
Output is locked to JPEG, so the binary search adjusts quality first and only reduces pixel dimensions if quality alone can't reach the target, re-encoding until the file lands at or just under 80KB — there is enough headroom here that even detailed photos keep their sharpness.
Need a different KB target?
If your portal asks for a different limit, the Target Size field stays fully editable — type any other KB value instead of the 80KB this page starts with.
Compress JPEG to 80KB in One Step
This tool is Compress JPEG pre-set to a 80KB target, so there's no mode to switch and no slider to guess with — drop your file and output is locked to JPEG, so the binary search adjusts quality first and only reduces pixel dimensions if quality alone can't reach the target. Everything happens locally via the Canvas API, so photos and ID documents never leave your device.
When 80KB Is the Number a Portal Asks For
An 80KB ceiling shows up repeatedly across resume attachments, document scans, and application-form photo fields — files over it are rejected outright, often without saying by how much. Rather than repeatedly saving at guessed quality settings, this page starts already locked to 80KB, so the first attempt is the only attempt needed. JPEG's lossy encoding means quality is the primary lever — each re-save after this one will cost a little more detail (generation loss), so always compress from the original file.
Switching Targets or Formats
If your form specifies a different KB limit, the Target Size field on this page stays fully editable — type any value and the same search applies. For format conversion or batch processing multiple files, the full Compress JPEG tool covers the same engine with every mode exposed.
Frequently asked questions
How do I compress a JPEG to exactly 80KB?
Drop your JPEG here — Target Size mode is already set to 80KB, so the tool immediately searches for the largest file that still fits under that limit.
Will my JPEG be uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API — the file never leaves your device.
Can I change the target away from 80KB?
Yes — the Target Size field stays editable, so you can type any other KB value if a different portal needs it.
Will compressing to 80KB visibly hurt quality?
There is enough headroom here that even detailed photos keep their sharpness; the live preview shows the exact result before you download.
