Hi thomman, thanks for your help, your link say buy a prestashop modul?? Any free modul for it?? 

[Thommen]

There are no free modules, they are only paid.

Hello @Thommen,

In this case you have 2 ways:

1) Convert your image to other allowed formats

2) Modify core of PrestaShop to upload your format.

@HelperPro

I gave the solution, only my post was deleted

 

[PrestaServicePro]

And it means, you have already solved the problem. Congratulations.

Hi both, 

 

Modify core prestashop is not possible for me 🙃, i don't have the know for it. 

This is the code, rigth? 

find. name "*.png" | xargs -I {} cwebp {} -o {}

 

Regards

This is a CLI command that you enter after connecting via SSH. You can set it in crontab to automatically search and replace image files. Remember that the command is for PNG files. You can extend it with additional extensions. The host must support cwebp from →  https://developers.google.com/speed/webp

You can also modify the filemanager code so that it can handle webp on import, like this: Image Attached

Files changed : 

• /admin/filemanager/ajax_calls.php
• /admin/filemanager/config/config.php
• /admin/filemanager/upload.php

At this moment the best solution is jpeg / png and module to convert to webp.

that's what i did thank you

I would not use webP files as long as there are even 2 % on browsers not recognising that file format.

Further it's a Google format, most likely they collect data from it.

[Thommen]

find ./ -type f -name '*.jpg' -o -name '*.png' | xargs -P 9 -I {} sh -c 'cwebp $1 -o $1 || true' _ {} \;

Hi,

Thanks to NicolasV for the solution. Answered for me in Prestashop 1.6. you have to do is change the code mentioned in .htaccess, put the webp read code of the web server and delete the PrestaShop cache once. Good luck

Hi,

Likewise here!

Would need a solution for 1.7.x

I think it's worth a try, especially since the solution I implemented is in production on a 1.7 (and working).

[Sickboards]

Although I don't understand the 

&& $info['extension'] != "webp"

part in upload php (I would have expected something like:

|| $info['extension'] == "webp")

I can confirm it is working in 1.7.5.4

[Dennismax]

I can't get to work in 1.7.8.7 😕 

Did I do somethings wrong ? 

[Nickz]

In case of having a shop which actually works, stick to jpg as long as webP is not 100% accepted in all browsers. WebP is from Google, a format from Google I'd not advice to use, same goes with Google Fonts. Just mediums to spy on us.

I tried your solution in version 1.7.8.7 but it doesn't work. I also tried clearing the cache but nothing. Do you have any suggestions?
Thanks in advance

If you are a seller, switching to WebP might be a big factor in getting your site load times better (depending on what format was used earlier) and ranking better in Google CWV's which again can be ntoceable amount of added revenue. Also JPG's don't support transparency which is why many use PNG and the diference between PNG an WebP is significant.

Hey everyone,

I know this is an old topic, but it's the first result on Google.

From my experience, editing the core is generally a bad idea

- it messes up the future upgrades

- in this specific case, the proposed solutions, as @Nickz fairly pointed out above, may not be 100% compatible with all browsers

(While I agree with the point about Google collecting as much data as they can, the webp unlike fonts is not hosted on Google servers, and instead is a yet another file on our servers, so shouldn't be a problem?)

So what I think could be a good way out is, as they say, "graceful fallback", as described here:

- https://serverfault.com/questions/630212/conditionally-serving-high-resolution-and-webp-images-with-nginx

- https://alexey.detr.us/en/posts/2018/2018-08-20-webp-nginx-with-fallback/

For it to work you will have to have your shop served on a proper server with Nginx and have basic understanding of how to configure it. I won't copy the whole thing here, but the general idea is

- you run a command (or schedule a script) to generate and have *.webp files alongside your regular images

- you configure the webserver to look at the accept header coming from the client's browsers: if webp is mentioned there, then it serves the webp copy, otherwise business as usual

We have done it like this in our shop and it's been running perfect for well over a year. Kudos to whoever came up with the idea first! (I would give a better credit if I could figure out who it was.)

WebP is now officially supported in new Prestashop 8.0.0!
