@Vivaldiscool "Request entity Too Large" ist the proxy server message for such issues.

@Vivaldiscool said in ISSUE: I cannot upload any themes to vivaldi://settings/themes:

I do not know how to change the size of the file / .zip file.

Well, clearly your zip has too much big resources to be uploaded.
Review your theme. Likely you have very big icons (>64/128) or not well optimized animations (gifs/webp).

[Vivaldiscool]

@Hadden89, As you said:

big resources

Here is the size of the files.
Most icons at <2 KB;
Some icons are more than but, 35> KB;
.json / code: 1 KB;

.gif / background: 22,015 KB escatly.

@Hadden89, As you said:

animations (gifs

The .gif/background file is 22,015 KB escatly, I do not know how to make it smaller.

[DoctorG]

@Vivaldiscool Why so large?
Try to resample with ScreentoGif in size and palette.

[Vivaldiscool]

@DoctorG, As you said:

Why so large?

Animation, no idea the actual reason.

[Vivaldiscool]

@DoctorG, As you said:

ScreentoGif

What is that?

[DoctorG]

@Vivaldiscool A program to create screenrecordings and edit/resampling existing animations/videos.

[Vivaldiscool]

@DoctorG, Okay downloading it.

[DoctorG]

@Vivaldiscool It is a nice tool, easier to use than commandline ffmpeg with its many options

[Vivaldiscool]

@DoctorG, no idea how to use it... is their a support website or something? (I installed it fully, I think.)

To many frames, top large width/height, unreduced palette.
I thought webdevs knew about what GIF is
I learned such 1999 as a multimedia pro.

[Vivaldiscool]

@Hadden89 Every frame is about 66 MS.

@Vivaldiscool The timing of the frames doesn't matter much in terms of file size. That is just how long each frame is visible.

Along the top bar, under Edit, you can use Remove Duplicates and Reduce Frame Count to get rid of extra frames. Under Image, you can use Resize or Crop to shrink the size of the frames.

And under File, when you select Save As to export the GIF, there are several settings that can help. Reducing the number of colors it is allowed to use and enabling Detect unchanged pixels should help.

@Vivaldiscool Might help if you shared the ZIP file you're trying to upload and let us check it here.

Your GIF file is probably much too large.

Although, these days I would suspect a well-compressed MP4 would in fact take up less space than a GIF and look much better - and might even have less CPU overhead. But GIFs is all that's allowed in themes...

[Vivaldiscool]

@Pathduck, Size of files.

@Vivaldiscool Hi, did you solve this?

If you did, please mark your topic as Solved.

[Vivaldiscool]

@Pathduck No, not yet.

[Pathduck]

@Vivaldiscool Sure, but if it's caused by you being unable to make a theme that fits within the limits it should be marked as solved.

The guide states:
Processing the theme failed. How do I fix it?
Alternatively, the theme file (ZIP) might be too big (due to the background image) or the background image is in an unsupported format. Resize or replace the background image, create a new ZIP file and upload the theme again.

Which file formats are accepted for the background image and what's the size limit?
The background image can be in the following formats: JPG, JPEG, PNG, GIF, WEBP.
The image size should stay below 8MB.

So there's nothing Vivaldi can do about you creating too large a theme.

[Hadden89]

The only solution I see is to upload the theme without the background (or with a static one) and link the mp4 animated wallpaper externally (mega/gdrive/ecc) with all its high resolution. Also, converting it as a GIF never was a good idea: the format was born with 256 colors and low frame rates. So, very very poor compression ratio.
