How to compress images online without losing quality?

Use the free Image ToolKit compressor. Adjust quality from 10% to 100% and choose JPEG, PNG or WebP format. All processing is done locally in your browser — no file is ever uploaded to any server. You can also compress multiple images at once with batch mode.

Can I crop and resize images for free without uploading?

Yes. The crop tool uses an interactive selection box with preset ratios (1:1, 4:3, 16:9) and manual width/height input. The resize tool supports custom dimensions with aspect ratio lock. Everything runs 100% client-side — your images never leave your device.

How to convert HEIC photos to JPEG or PNG online?

Image ToolKit supports HEIC (Apple iPhone photo format) input in the Convert panel. Simply upload your HEIC file, choose JPEG, PNG, WebP or BMP as the output format, adjust quality if needed, and download. No upload to any server — conversion happens entirely in your browser.

How to censor, blur faces or pixelate parts of an image online?

The Censor tool (also called Mosaic or Pixelate) lets you apply a pixelation effect with adjustable block size from 2 to 100 pixels. Use it to blur faces, hide license plates, censor sensitive text, or create mosaic art effects. Real-time preview, free, no upload required.

What image formats does this free online tool support?

Input: JPEG, PNG, WebP, BMP, HEIC (Apple photos), and most common image formats. Output: JPEG, PNG, WebP, BMP. The converter panel handles format switching, the compressor adjusts quality, and all tools produce clean, optimized output files.

Is it safe to use browser-based image tools? Are my images uploaded?

Absolutely safe. Image ToolKit uses the browser's Canvas API to process everything locally. No image data is ever sent to any server or third party. You can disconnect from the internet after the page loads and all tools still work perfectly. Your privacy is 100% guaranteed.

How to add a watermark to multiple images at once?
