Frequently Asked Questions
How do I compress an image without losing quality?
Use WebP format at 80–85% quality — it gives 25–35% smaller files than JPEG at the same visual quality. For truly lossless compression (zero quality loss), use PNG. PixlFits lets you drag the quality slider or set a target file size and automatically finds the best quality setting.
How much can I reduce an image file size?
A typical JPEG photo can be reduced by 40–70% with no visible quality loss at 80–85% quality. WebP format reduces file sizes a further 25–35% compared to JPEG. For example, a 3 MB JPEG often becomes a 700 KB WebP with identical visual quality.
Does PixlFits upload my images to compress them?
No. PixlFits compresses images entirely in your browser using the HTML5 Canvas API. Your images are never sent to any server, stored anywhere, or seen by anyone. This is the same technology used to compress images in professional photo editing software — it just runs in your browser tab instead.
Which format gives the best compression — JPG, WebP, or PNG?
WebP gives the best file size vs quality ratio for photos and is supported by all modern browsers. JPG is the most compatible format, works everywhere, and is slightly larger than WebP. PNG is lossless — it never reduces quality — but produces larger files for photos. Use PNG for screenshots, logos, and graphics with text.
Can I compress multiple images at once?
Yes. Drop multiple images onto PixlFits or click Browse and select several files at once. All images will be compressed with your current settings and you can download them all as a single ZIP file.
