01
How to use this tool
Set the balance
Choose a quality level for JPG or WebP. PNG is re-encoded without a quality slider because browsers do not offer meaningful PNG quality control.
Review and download
Compare file sizes and download one result or a ZIP of the batch.
02
Built for predictable results
Private by default
Encoding happens in your browser, not on an upload server.
Clear settings
Only controls that affect the selected output format are shown.
Reliable batch processing
One failed file does not stop the rest of your queue.

Frequently asked questions
Does Pixlery upload my images?
No. Supported images are processed locally in your browser. Pixlery does not receive your files.
Will compression change image dimensions?
Not by default. The compressor keeps the original pixel dimensions unless you enable a maximum dimension.
Why is there no PNG quality slider?
Browser PNG encoding does not use the same quality setting as JPG or WebP, so Pixlery does not show a control that would not change the result.
Why can a result be larger?
Some files are already highly optimized. Pixlery shows the real result so you can keep the original when it is better.
Why did my PNG get larger?
Keeping PNG format re-encodes the image in your browser. An already optimized PNG can become larger after re-encoding. If the result is bigger, keep the original—or try WebP or JPG for photos.
What does the JPG background color do?
JPG cannot store transparency. The background color only replaces transparent pixels when you export PNG or WebP as JPG. Images without transparent areas look the same regardless of the color you pick.
