Built for strict 100KB upload limits
Some use cases on the web have a strict size limit for image uploads - profile avatars for discord, or forums, student ID picture among others.
Default 100KB Setting:
Start with the target already configured, which removes the trial-and-error common in generic compressors.
Useful for Forms:
Prepare photos for application portals, school forms, exam forms, ID systems, and profile uploads that reject larger files.
Format-Aware Compression:
Use JPG for most photos, PNG for graphics or transparency, and WebP when the upload destination supports it.
Pixel Resizing Included:
If the same form also asks for dimensions, combine the 100KB target with pixel resizing before export.
No Server Uploads:
Images are processed on your device, which is important for personal photos and identity documents.

In case you have varied file size requirements across different websites, you can use our dedicated image KB reducer to dial in the exact kilobyte or megabyte target you need.
