How much can I reduce image size?
Photos usually shrink by 60–90% at 70–80% quality with no difference visible on screen. Setting a maximum width (for example 1920px) helps most with large camera photos.
Which output format should I choose?
WebP gives the smallest files and is supported by all modern browsers. Choose JPG for the widest compatibility, or keep the original format if you are unsure.
Frequently asked questions
Does compressing reduce image quality?
Slightly, but at 70–85% quality the difference is almost impossible to see while the file becomes much smaller.
Is there a file size limit?
You can compress images up to 50 MB each, and up to 100 images per batch.
Can I compress PNG images?
Yes. For the biggest saving, convert PNG photos to WebP or JPG. Keep PNG for graphics that need transparency.
