What is an online image compressor?

An image compressor reduces the file size of digital pictures (JPG, PNG, WebP) by optimizing color palettes, removing unnecessary metadata, and adjusting compression encoding.

Can I compress images to an exact target KB or MB size?

Yes! PDFLOL features an intelligent binary search engine that iterates through compression quantization to hit your exact target kilobyte or megabyte threshold for government and job portal uploads.

Which image formats can I compress?

You can compress JPG, JPEG, PNG, and WebP graphics, and export them in your preferred format.

Can I compress multiple images simultaneously?

Yes. PDFLOL supports batch compression allowing you to upload multiple photos at once and download them individually or bundled as a single ZIP archive.

Are my photos uploaded to a cloud server?

No. All compression algorithms run locally inside your browser using HTML5 Canvas. Your images are never transmitted or stored on remote servers.
