Frequently asked questions
Does compression reduce image quality?
At 80-90% quality, the file shrinks significantly with no visible difference. You can preview the result before downloading and adjust the quality slider until you're satisfied.
Is there a file size limit?
No. Your device memory is the only limit. Unlike TinyPNG (5 MB free limit) or other upload-based tools, ImgPrism processes everything locally with no server restrictions.
Are my images uploaded to a server?
No. All processing happens in your browser using the Canvas API. Your images never leave your device. Close the tab and they're gone from memory.
