Frequently asked questions

How do I get my image under 100KB?
Convert to WebP and lower the quality slider. Each file shows its compressed size, so you can stop as soon as it drops below 100KB.
What if my image can’t reach 100KB?
Very large or highly detailed images may stay slightly above 100KB even at low quality. Resizing the image’s dimensions first will help.
Does it work for JPG, PNG and HEIC?
Yes. Drop in any common image format and compress it toward the 100KB target.
Is my image uploaded?
No. The whole process runs in your browser, so your image stays private.
