Frequently Asked Questions
What can this image compressor do?expand_more
The compressor can handle plain quality-based compression, aim for a target file size like 20KB or 50KB, and export exact dimensions when you enable the resize controls. All processing happens locally in your browser.
Does this tool upload my photo anywhere?expand_more
No. The image is processed locally with browser APIs and Canvas. Nothing is sent to a server.
Can I prepare exam photos here?expand_more
Yes. You can use the built-in dimension presets for common exam and document sizes, then optionally aim for the file-size limit your form requires.
Will PNG and HEIC files work?expand_more
Common browser-supported image formats work. The output can be normalized to JPG, which is the most widely accepted format for exam uploads.
