Compress an Image to Under 100KB
Meet a strict 100KB cap with verified output and automatic dimension reduction when quality is not enough.
Use the verified 100KB presetDirect answer
Set a 100KB hard limit. PixCloak searches for the highest acceptable quality, reduces dimensions only when needed, and rejects any output that still exceeds 102,400 bytes.
This guide's before-and-after files
1200×800 · 530.15KB · download file
819×546 · 91.66KB · download file
Actual output is 91.66KB at encoder quality 40; it decodes successfully.
Re-encoded locally and rejected until the file measured at or below 102400 bytes.Validation date: 2026-07-18. Both files are downloadable; dimensions, byte counts, decodability, and distinct SHA-256 hashes are checked by the repository test suite.
Use the verified workflow
- Choose the 100KB preset and preferred format.
- Process the file; allow dimensions to fall if quality alone cannot meet the cap.
- Download only after the actual size and decode verification are shown.
Limits and failure cases
- Very detailed images may need much smaller dimensions.
- PNG can be inefficient for photographs; JPEG or WebP may preserve more detail under 100KB.

Common question
Does PixCloak upload the source image?
No. The editing pipeline uses browser File, Canvas, and Blob APIs on this device. Optional analytics and advertising are separate and load only after the applicable consent choice; product events never include image bytes or filenames.
