Compress images without wrecking the quality
Large images are the most common reason a WordPress site feels slow. Compressing before upload means every generated thumbnail size starts smaller too, so the saving multiplies across your whole media library.
Common questions
How small should a WordPress image be?
For full-width hero images, aim under 200KB. For in-post images, under 100KB is comfortable. Thumbnails should be well under 30KB. These are guidelines, not rules — a photographic header justifies more weight than a screenshot does.
Will compressing damage the image?
At 80% quality most photographs are visually identical to the original at a fraction of the size. Screenshots, logos and anything with flat colour or sharp text suffer more from JPEG compression — keep those as PNG or WebP.
Are my images uploaded anywhere?
No. The processing happens in your browser using your own device. The files never reach WPFolks or any other server, which is also why it works on files far larger than any upload limit would allow.
