- Create a preview and download the finished image.
GOOD TO KNOW
A few useful details
Zero preserves each adjustment. PNG and WebP preserve transparency; JPEG uses your selected background color. Changes operate on decoded pixels and do not retain image metadata.
Image metadata is not preserved. Exports are still images, with orientation applied to the pixels.
Common questions
Are my files uploaded?
No. Processing happens in your browser. The site downloads its own code, fonts, and processing engines; it does not send your files or passwords to a processing service. Reset or close this tab to release files from the app.
What are the limits?
Up to 40 MB per file and 80 MB in total. Compress Image and Convert Image accept up to 50 input images; other tools have their own file-count limits. PDFs are limited to 200 pages and images to 24 megapixels. Available device memory can impose lower practical limits. Try smaller batches on a phone.
Will my original file change?
No. Each tool creates a new output for you to download. Review the preview and downloaded result before relying on it, especially for important or signed documents.
