The Transform screen : Redimensioning books
The Transform screen can be used for two different purposes :
- Resizing : Changing dimensions of all pictures of a given book
- Transcoding : Changing the encoding of all pictures of a given book
You can perform either of them, or even both at once.
- Turn the "Resize pictures" switch on
- Choose the resizing method
| Method | Description |
|---|---|
| Max X% of screen dimensions | Downscale each picture so that its width (or height) is X% of your device's screen width (or height) |
| Absolute max dimensions |
Mangas : Downscale each picture so that its height is the specified value. Manhwas/webtoons : Downscale each picture so that its width is the specified value NB : A picture is considered to be a manhwa/webtoon when its height/width ratio is > 3 |
| % of original image size | Downscale each picture to a given % of its original dimensions. |
| AI upscale 2x | Upscale each picture by a 2x factor using the Real-CUGAN AI model. Processing will use your GPU intensively and may take a few minutes. |
All of these methods preserve the width/height ratio.
- See how your settings apply to the current book's images by taking a look at the preview
- Hit the "Transform" button
- Choose which method to use
| Method | Description |
|---|---|
| Use the same encoder for all pictures | Transcode all pictures using the same encoder |
| Differentiate lossless and lossy pictures | Transcode lossless pictures with a lossless encoder, and lossy pictures with a lossy encoder |
- Choose which encoder to use
- If you chose a lossy encoder, set its quality

Animated pictures aren't supported yet - see https://github.com/avluis/Hentoid/issues/1069
Transform started by using the encoders available out of the box on Android : JPEG, PNG and WEBP.
If you need another encoder, you're welcome to open a GitHub issue and give us the link to a library to integrate to the app.
