Client-Side Social Media Image Compressor (WebP, JPEG & PNG)
Social platforms aggressively re-compress oversized uploads, introducing muddy artifacts to your photography and text graphics. Compress and convert images to WebP, JPEG, or PNG locally in your browser with real-time file size calculation before you post.
Aim to keep social feed uploads under 1 MB (and YouTube thumbnails under 2 MB) so platforms skip their harshest server-side re-encoding pass.
If PNG output size does not change when moving the quality slider, switch to WebP or JPEGβPNG is a lossless format and ignores lossy quality percentages.
