Paste Images As WebP

Description
An Anki add-on that makes your images small.
We all know that people who don't store their images in WebP are wasting a lot of disk space. Not only on their hard drives, but on AnkiWeb as well. Unfortunately Anki doesn't convert images to WebP when you paste them from elsewhere, and it takes time to convert and resize images manually.
For the longest time I used a bash script to automatically convert images in my Anki collection to WebP until I decided that we simply need an add-on for this.
WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.
Storing images in WebP is a great way to reduce the size of your Anki collection.
Configuration
To configure the add-on select AJT > WebP settings from the top menu bar.
Usage
Watch the video demonstration:
After installation images will be automatically converted to WebP and resized on drag-and-drop. There's also a button in the Editor toolbar that lets you do the same.
To bulk-convert existing images in your collection, select Edit > Bulk-convert to WebP in the card browser. You can see how it's done on 
.
To rename media files on a particular note, open the Anki Browser, select the note and click on the pencil icon on the toolbar. A dialog will pop up asking you to enter new filenames. A demo showing how it's done is also available on .

Excellent !!! Brillant !!! Effective !!!

Essential for people with low storage, mainly in mobile devices

Please add option to preserve aspect ratio and crop to `max_side_size`.
E.g., for image with `1200x600` or `1200x600` and `max_side_size = 1000`, we have `scale_ratio = max_side_size / max(1200, 600) = 1000 / 1200 = 5 / 6`.
I.e. `1200x600 → 1000x500`, `600x1200 → 500x1000`
Right now, if one specify `max_image_height = max_image_width = 1000` and convert `1200x1500` image, one get deformed `1000x1000` result.

Great idea, and very handy!
I'm wondering if its normal though, that all images become blurry if i do any kind of resizing when i paste the image? Even if i keep the aspect ratio constant.

Thank you for the feedback! If you crank image quality, the blurriness should go away.

its a really good addon, Idk why but for me it can't convert some of the pics
Comment from author
GIF files are not supported by cwebp.

Thanks for this amazing work of yours

Extremely useful add-on, this should be default in the future

Great add on, but as one other commenter has mentioned - why not AVIF if it's the better/more futere-proof format?
Comment from author
Anki and many other programs do not support this format yet. Maybe in the future.

Is there also a solution for gifs? audios?

thumbs up before using: how much % space will this save? i have over 50k images in my deck, several GB.. are transparent images transparent after converting? WebP work with ankidroid? please let me know id love to save space and they will probably load faster too? i want to use this to convert my entire 50k images but dont want any nightmares of messing up my working system
Comment from author
> how much % space will this save?
depends on your settings, but you can reduce the size by as far as 9 times, though the image quality will suffer.
> are transparent images transparent after converting?
By default - no, because transparency wastes disk space. But you can disable the blend_alpha option in the config.json file.
>WebP work with ankidroid?
Yes.

Great addon! This should really be default in Anki, don't know how much they are paying to maintain the storage, but it would surely help.

Works like a charm & is extremely effective! Love the fact you can completely configure it to your own needs and have the option to be asked for the settings with every insertation or not.. This really optimises the use of images in Anki indeed.
Thanks for introducing me to WebP and for your wonderfull add-on. It would be great if you have the option to determine the name of the image when pasting, so its management would be complete without the need for another add-on to rename the auto-generated file name.

Amazing addon! Thank you so much! Just an idea: It would be really nice if there was a bulk convert option, I don't know if it's possible though. Edit: Thank you so so much!

I appreciate your review, and thanks for the amazing idea! It has been implemented in the latest release.

Does this convert already existing images in collection.media? I use the Bulk Fetch Images from Google addon and was wondering if it could auto convert all the images this addon downloads. Great addon!
Comment from author
The add-on deliberately avoids processing internal pastes. Otherwise using Anki would become a nightmare ;)
However, in the latest release it is possible to bulk-convert images. To do it select the cards you want to process and press Edit > Bulk-convert to WebP.

Nice plugin, thank you! Just one thing: Would it be possible to add an option for not upscaling images when pasting images lower than the specified sizes automatically, similar to the "ImageResizer" add-on? They could of course still be converted to webp though.

This is a wonderful idea! Why don't we ask damien to implement it natively?
