When to use Compress Image to 1 MB
Use this target when a form allows up to 1 MB per image. The converter searches quality levels without changing dimensions and picks the best result at or below 1,000,000 bytes when possible. PNG input becomes JPG with transparent pixels filled white.
Quality and file size
A small image may already be under the limit and remain unchanged in size or quality. Large or detailed files may still exceed it; resize first if compression alone cannot reach the target. PNG transparency is not retained.
Frequently asked questions
Does the output always reach 1 MB?
The target is a maximum. Files already below it stay below; very detailed images may fail to reach it.
Does compression change dimensions?
No. It searches encoding quality only.
Which input formats work?
JPG and WebP keep their format. PNG input is encoded as JPG, with transparent pixels filled white.
Are files uploaded?
No. Compression runs locally in this browser tab.
