Frequently Asked Questions
Is image compression free on Pixotter?
Yes. Compress unlimited images for free with no signup. Free tier supports up to 20 images per batch (10MB each). Processing happens in your browser — your images are never uploaded.
How does browser-based compression work?
Pixotter compresses your images directly in your browser. Your image never leaves your device — it's loaded into memory, compressed, and downloaded without ever being uploaded to a server.
What image formats can I compress?
Pixotter compresses JPEG, PNG, WebP, AVIF, GIF, TIFF, and BMP files. Each format uses its own optimized compression algorithm — for example, JPEG uses quality-based lossy compression while PNG uses lossless optimization.
What quality setting should I use?
For photos, 75-85 gives the best balance of file size and visual quality — most people cannot tell the difference from the original. For screenshots or graphics with text, try 85-95 to keep sharp edges. Use the before/after slider to preview the result before downloading.
Can I compress and resize in one step?
Yes — that is Pixotter's core feature. Use the pipeline configurator to check both Compress and Resize (and any other operations). The image stays in browser memory between steps, so there is no re-upload needed.
