How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
Some sites set the profile picture limit just above 50 KB, and some people want slightly more room than the 50 KB tier gives. At 55 KB the face keeps fine detail around the eyes that a smaller file tends to lose.
The compressor tries quality settings from high to low and picks the best one that fits. If the picture is large, it also scales it down, and the result row shows both the new size and the new dimensions.
A profile picture is usually shown small, so its job is to be recognisable at a glance. A close crop with a plain background does that better than a wide shot with a lot of scenery.
Faces at 55 KB
Fifty-five kilobytes is 440,000 bits, which supports about 660 by 660 pixels of an ordinary picture. Avatars are rarely shown larger than 200 pixels, so there is plenty of room to keep the picture sharp after the site scales it down.
Square crops for round frames
Most sites cut a profile picture into a circle. Crop to a square with the face in the middle before you compress, and leave some air above the head. A good square crop wastes no bytes on corners that will be cut away.
Avoiding double compression
Some platforms recompress what you upload. If you send a heavily squeezed file, their pass adds new damage on top of yours. Giving them a clean 55 KB file with a reasonable pixel size means the second round has little left to hurt.
Group photos and wide shots
A group photo has many faces and cannot be cropped tight. At 55 KB it will look acceptable on a phone but soft on a desktop monitor. For a group shot, consider raising the target to 100 KB so every face keeps its detail.
Logos and icons
A logo is mostly flat colour with sharp edges, and 55 KB is far more than it needs. If the logo has a transparent background, choose PNG or WebP. If the result is well under 55 KB, you can enlarge the logo in Resize and keep it crisp for bigger screens.
Never save a logo as JPEG at low quality, because the edges of letters pick up visible noise.
Recompressing an old picture
If your only copy is already a compressed JPEG, go gently. Each round of lossy compression adds new blocks and blur. Choose a target close to the current size, and where you can, go back to the original camera file and compress it once.
We do not list other services' limits on this page, because they change. Rely on the wording on their own site.
Recompressing an old picture
If your only copy is already a compressed JPEG, take care. Each round of lossy compression adds new blocks and blur. Pick a target close to the current size and, where you can, go back to the camera original and compress it once.
Copies that came through messages and social networks have usually been compressed already.
Frequently asked questions
Is 55 KB too large for a profile picture?
That depends on the site. Check its stated limit and use Custom if you need a different number.
What size should an avatar be in pixels?
Between 400 and 600 pixels square is plenty for most avatar frames.
Can I upload a transparent logo?
Yes. Use PNG or WebP so the transparent areas stay transparent.
Does the tool change the colours?
Colours are kept as they are. Strong compression can band smooth gradients, but it does not shift the hues.
Can I make a picture bigger than its original?
The tool does not add detail. Enlarging a picture only stretches the pixels it has.
