How it works
- Drop your images or a folder.
- Choose a ratio, then crop it or keep the whole image with a background.
- Apply it and download the result, with your folder structure intact.
Crop or add a background?
Crop keeps the image full-bleed and removes what falls outside the new shape, measured from the center. Use it when the subject sits in the middle of the frame.
Add background keeps every pixel of the original and fills the empty space with a color or a blurred copy of the image. Use it for products, artwork, and anything that should not lose its edges.
Which ratio for which platform
Use 1:1 for square posts and marketplace listings, 4:5 for portrait feed posts, 9:16 for Stories, Reels, Shorts and TikTok, 16:9 for YouTube thumbnails and presentations, and 3:2 for standard photo prints. Platforms change their specifications, so check the current one for an important campaign.
No quality loss from resizing
Changing the ratio here never rescales your image. Cropping only removes pixels, and adding a background only adds them, so the image itself stays at its original sharpness.
Questions
Will my image be stretched?
No. FolderPix only crops or adds a background, so nothing is ever stretched or distorted.
Can I change the ratio of many images at once?
Yes. Drop several images or a folder and the same ratio applies to all of them. Free batches hold up to 10 images.
Can I choose which part stays when cropping?
The crop is centered for now, so the middle of the image is kept. If the subject is off-center, adding a background keeps the whole image instead.
Are my images uploaded?
No. The image is decoded and processed by your browser, on your device. FolderPix has no upload endpoint at all, and the site tells browsers to refuse connections to other servers. You can check it in the Network tab of your browser’s developer tools, or by going offline once the page has loaded.
