Examples use the bundled photograph by Michal Janek. Photo credit and license. Open your own image above to edit it locally.

How to use original comparison

  1. Open a photo and select an effect. This page starts with Risograph on the bundled sample.
  2. Hold the Original button or the Space key to inspect the original; release it to return to the effect.
  3. Choose Fit for the composition or 100% to inspect the image at its actual layout size. Frame and crop settings stay in place during comparison.

What to know

Very large images can use a reduced-resolution preview, including at 100%. The interface discloses this, and export still uses the selected output resolution within browser limits.

Files and export

Open a PNG, JPEG, or WebP with the file picker, drag-and-drop, or clipboard paste. All image processing happens on your device. Choose PNG or WebP to preserve transparency, or JPEG to flatten it onto a color. Exports use the original image resolution plus the frame unless you choose a smaller size.

A modern browser with WebGL2 is required. Browser and GPU limits can prevent very large exports; picshader explains the limit and offers a smaller size. No account or watermark is required.
