Frequently Asked Questions (FAQ)
How much can I reduce my file size?
Usually between 50% to 90% depending on the format and detail of the image. Standard photos can be heavily optimized without noticeable quality loss.
Does it support batch image compression?
Yes, if you need to convert, merge, or compile multiple images into a single PDF or other formats at once, check out our Batch Image to PDF & Format Converter tool.
Are my private photos sent to any servers?
Never. The compression is computed entirely in your browser memory via JavaScript and local canvas contexts. No data leaves your machine.
