How to Compress an Image Without Losing Quality
Practical settings for reducing image file size while keeping photos and graphics sharp.
Start with the right format
Photos usually compress best as JPEG or WebP. Graphics, screenshots and images with transparent backgrounds are usually better as PNG or WebP.
If your upload form accepts WebP, try it first. It often gives a smaller file than JPEG at the same visible quality.
Use a target size
When a form asks for a fixed limit like 35 KB, set that target directly instead of guessing quality values.
If the image still cannot reach the requested size, reduce the pixel dimensions first and then compress again.
Avoid repeated exports
Every lossy export can remove detail. Keep the original image safe, make one resized version, then export the final compressed file once.
