How it works
- Drop your images or a folder.
- Enter a maximum file size, or pick a quality level.
- Apply it, compare before and after, and download.
How the exact-size mode works
Enter a limit, for example 200 KB. FolderPix tries several quality levels and keeps the highest one that fits. If the lowest acceptable quality is still too heavy, it also reduces the dimensions, and it tells you when it did.
This is useful for forms and portals with strict upload limits, such as ID photos, job applications and government sites.
What happens with PNG files
PNG is lossless, so it has no quality setting to lower. In exact-size mode, PNG files are saved as JPEG, and any transparency is flattened on white. Choose WebP if you want smaller files and your destination accepts it.
Check the result before downloading
The preview shows the compressed result with its real file size. Drag the line across the photo to compare it with the original, and hover to inspect the pixels at actual size, where compression artifacts first appear.
Questions
Can I compress an image to 200 KB, 100 KB or 20 KB?
Yes. Type the size you need. Very small targets also reduce the dimensions, because quality alone cannot reach them without visible damage.
Can the file get bigger?
Not with the quality setting: if re-encoding would make a file heavier and nothing else changed, FolderPix keeps your original.
Can I compress many images at once?
Yes. Drop several files or a whole folder. Sub-folders are kept in the output. Free batches hold up to 10 images.
Is camera metadata kept?
No. EXIF data, including GPS position, is removed from images that are re-encoded, which also saves a little space. A file returned unchanged keeps its original data.
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.
