Tips for better results

  • Use a smaller test image before processing a very large batch.
  • Check important edges, text, and color after downloading.
  • Keep source files because canvas exports generally discard metadata.

FAQ

How does Batch Compress Images handle my source file?

Batch Compress Images reads the selected file in the current browser tab and creates a separate downloadable result. It does not upload the source image.

Does Batch Compress Images preserve EXIF metadata?

Pixel-based canvas exports normally omit EXIF, GPS, and camera metadata. Filename-only ZIP processing keeps the original image bytes and their embedded metadata.

Why might Batch Compress Images fail on a very large photo?

Browsers limit canvas dimensions and memory. The page rejects an unusually large pixel workload before it can freeze the tab.

Which input formats work with Batch Compress Images?

PNG, JPEG, and WebP are the most dependable inputs. Other formats work only when the current browser can decode them.

Can I use output from Batch Compress Images in commercial projects?

The processing does not grant new image rights. You still need permission for the source image and any names, logos, or notices included in the result.
