How to compress an image to your chosen size
- 1
Add your image
Choose a JPG, PNG, WebP, AVIF, HEIC, or JXL image. You can process a full batch in one pass.
- 2
Fit an editable byte limit
PixSip searches encoder quality first, then proportionally reduces dimensions only when needed to satisfy an editable byte limit.
- 3
Check and download
Review the exact output size and download one file or the whole batch as a ZIP.
Exact size without trial and error
A real byte ceiling
The output is measured against an editable byte limit, not a rounded estimate shown after encoding.
Highest useful quality
A binary search keeps the highest encoder quality that fits before any resolution reduction is attempted.
Private local processing
Sensitive signatures, ID scans, and application photos are encoded on your device and never uploaded.
