Common Questions
Are my images uploaded to a server?
No. All compression happens entirely within your web browser using WebAssembly and
modern web APIs. Your files never leave your device, ensuring 100% privacy.
How is this free? Are there hidden limits?
Because the server doesn't process the images (your computer does all the work!), our
hosting costs are essentially zero. There are no artificial limits on how many images you can compress.
Does it work offline?
Yes! Once you load the site for the first time, it installs a Service Worker that
caches the app. You can disconnect from the internet and continue compressing images.
What is the maximum file size?
We recommend keeping individual files under 20MB to ensure smooth processing without
crashing your browser tab, but there are no hard server limits since everything is local.
What format should I choose?
For web viewing, WebP or AVIF offer the best
compression. If you need maximum compatibility, stick with JPEG (for photos) or
PNG (for graphics).
How do you achieve such high compression for PNGs?
We use a combination of the Canvas API and advanced lossy compression techniques,
achieving high level file size reduction while maintaining stunning visual quality.
Is my original image overwritten?
No, your original files are never altered or damaged. IMGPRESS creates new, optimized
versions of your images that you can download individually or together as a single ZIP file.
