Start with a copy
Compression changes the output file. Keep your original until you have checked the result at the size people will actually see.

Reduce image weight before you attach, share, or upload. Start with a copy so you can compare quality and file size before keeping it.

How to compress without a surprise
For a normal photo, lower quality in small steps and inspect the result. If you are sending an email, a smaller pixel width is often more useful than pushing the quality setting too low. Transparent images need a format that preserves transparency.
Frequently asked questions
Will compressing lose quality I can't get back?
Yes, lossy compression discards detail. Keep your original file and treat the compressed copy as a separate output for a specific purpose.
Is my image uploaded to compress it?
No. Compression happens locally in your browser. MorphoThat does not receive the file to process it.
What if the result is still too large?
Try a lower quality setting, or resize the image first — fewer pixels usually compress further than quality reduction alone.
Use the smallest useful size
Dimensions matter as much as quality. A large phone photo usually benefits from resizing before aggressive compression.
Resize firstKnow the trade-off
JPEG and WebP can reduce photo file sizes using lossy compression. Text, illustrations, and logos may look better as PNG.
