How do I add a filter to a photo in my browser?

Drop in a photo, then pick a filter from the thumbnails: B&W, Sepia, Vintage, Cool, Warm, Noir or Invert. Adjust Brightness, Contrast and Saturation if needed, then download. Processing happens on your device.

Can I adjust brightness, contrast and saturation after choosing a filter?

Yes. Sliders for Brightness, Contrast and Saturation run from -100 to +100, and there is an Intensity control. Press Reset to undo changes, or hold the compare button to see the original.

What file formats can I export, and what quality can I choose?

You can export JPEG, PNG or WebP. For JPEG and WebP, the Quality slider runs from 50 to 100, defaulting to 92. PNG has no quality setting.

Why did the transparent background of my image turn white?

JPEG does not support transparency, so transparent areas become white. Photos with transparency default to PNG when loaded. Choose PNG or WebP under Format to keep transparent areas.

Is there a maximum photo size, and why does it say it could not load my image?

Photos with a side over 4096 pixels are scaled down to 4096 pixels on the longest side. The error Could not load this image usually means the browser cannot decode that format.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.
