Start with your task
For a 200 KB upload limit, use Resize Photo to KB and choose 200 KB. For a specific pixel width, choose Resize Image. For a red/blue background, remove the background first if the image is not transparent, then continue to Change Background Color.
A file cannot be read
Check that the format matches the tool, the file is not empty and its download is complete. Renaming an extension does not convert file contents. Password-protected PDFs must be opened and saved without a password using an app you are authorized to access.
Slow processing or low memory
Try one file, choose a shorter page range or use a smaller image. Close other demanding tabs. AI/OCR engines need time to prepare models on first use. Keep the page open while processing.
The result looks different
Transparency becomes white when saving JPG. Low quality can cause artifacts. Resizing changes pixels, while target KB adjusts data size. For accurate physical ID-photo sizes, use the output PDF and print at 100% scale.
Install and use offline
Use Install UbahFile if supported, or follow the home-screen instructions. Installation and offline asset downloads are separate steps: click Prepare offline mode and wait for ready status. Background-removal AI still needs a connection for its initial model.
