Frequently Asked Questions
How does SlimPix compress images?
SlimPix uses advanced browser-based compression algorithms to reduce JPEG, PNG, and WebP file sizes. The compression happens entirely in your browser using Web Workers — your images are never uploaded to any server.
Is there a file size limit?
There is no strict file size limit. Since all processing happens locally in your browser, the only constraint is your device's available memory. Most modern devices handle images up to 50 MB with no issues.
Will compressing reduce the quality of my images?
You have full control over the quality setting. At the 'Balanced' preset (50%), most images look visually identical to the original while being significantly smaller. Use the 'Best' preset for near-lossless compression.
Can I compress multiple images at once?
Yes. SlimPix supports batch compression — select or drag multiple files at once. Each image is compressed individually, and you can download them all when finished.
What image formats are supported?
SlimPix supports JPEG, PNG, and WebP images for compression. You can also choose to convert between these formats during compression.
Is my data private?
Completely. All image processing runs locally in your browser using JavaScript. Your files are never uploaded, stored, or transmitted to any server. SlimPix has zero access to your images.
