Frequently Asked Questions
What happens to my images after compression?
Nothing. All processing runs in your browser using Canvas API. Your images never leave your device and are automatically deleted when you close the tab.
What is the maximum file size?
You can upload images up to 50MB. For very large files, compression may take a few seconds depending on your device.
Does compression reduce image dimensions?
No, compression only reduces file size by optimizing the image data. Dimensions stay the same unless you use our Image Resizer tool.
Can I compress images on my phone?
Yes. ResizeMint works fully on mobile browsers. All features including bulk compression work on iOS and Android.
What image formats do you support?
We support JPG, PNG, WebP, and GIF for compression. You can also convert between formats during compression.
