To be smaller as a webp image, the quality would have to be set to roughly 68 (out of 100) to be smaller. * The “Économies potentielles” that Pagespeed Insights list are purely estimations( a simple math formula), it’s not what they’re actually able to get it to. * Using a quality of 68 would simply make the image look really bad. * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12765857) * Thank you for your explanations 🙂 * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12765895) * [@lucasrolff](https://wordpress.org/support/users/lucasrolff/) * what is the extension . tmp ? * I just saw that all the images have this extension instead of .webp. * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12765910) * can I replace manually via FTP .jpg version to .webp version ? * 97,5 for jpg * and 97,1 for webp with [https://convertio.co/](https://convertio.co/) * [LucasRolff](https://wordpress.org/support/users/lucasrolff/) * (@lucasrolff) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12765915) * The only thing I can see in the code, would be when it fetches the images from the image optimization servers, if the checksum for comparing the image (if it’s intact) would be a “mismatch”, then it seems the .tmp files can be left over. * That would however, give a message of “Pulled image md5 dismatched” in the admin panel from what I can see. * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12765956) * Thanks you very much 🙂 * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12766045) * [@lucasrolff](https://wordpress.org/support/users/lucasrolff/) * what do you think about Lossless ? * 516 vs 56 ko !! * Thread Starter [espacemusculation](https://wordpress.org/support/users/espacemusculation/) * (@espacemusculation) * [5 years, 11 months ago](https://wordpress.org/support/topic/webp-image-problem/#post-12766046) * [@lucasrolff](https://wordpress.org/support/users/lucasrolff/) * what do you think about Lossless ? * 516 vs 56 ko !!
