Frequently Asked Questions

What is the best free image compressor that doesn't upload my photos?

ImgConvertPro compresses images entirely in your browser, so photos never leave your device, unlike upload-based tools such as TinyPNG or iLoveIMG. It's free with no sign-up, no watermark and no file limits, and shows a live before/after preview.

Are these image tools really free?

Yes, completely free. No subscription, no trial, no watermark, no account and no daily limits.

Do you upload my images to a server?

No. Every tool runs in your web browser using JavaScript, the HTML5 Canvas API and WebAssembly. Your images are never sent over the internet, which also makes the tools fast.

Can I compress an image to an exact size like 20KB or 50KB?

Yes. The compress-to-size tools search for the highest quality that fits your target (10KB to 2MB, or any custom value) and only reduce the dimensions if quality alone isn't enough.

Which formats are supported?

JPG/JPEG, PNG, WebP, HEIC/HEIF (iPhone), AVIF, JPEG XL, GIF, BMP, SVG and PDF as input; JPG, PNG, WebP and PDF as output. There is also OCR (image to text) in 12 languages.

Who makes ImgConvertPro?

ImgConvertPro is built and maintained by ZypiqLabs (zypiqlabs.com), an independent software studio that builds fast, private, browser-first tools.

Does it work on mobile phones?

Yes. Every tool works in modern mobile browsers, including Chrome on Android and Safari on iPhone. No app install needed.
