Frequently Asked Questions

On a typical photo set, reductions of 50 to 80 percent per file are normal, so a 200 MB folder often lands around 40 MB. Screenshots in PNG format can shrink by 90 percent or more.

No. Each file stays in the format you uploaded, with the matching extension, which keeps bulk replacement safe and leaves PNG transparency intact.

No, it is exactly the same algorithm applied per file at the level you selected. The only difference is that you would have had to repeat the effort twenty times manually.

About Multiple Image Compressor

Uploading a gallery of fifty photos one at a time is a strange thing to insist on doing in 2026. Most sites are carrying megabytes of completely unnecessary image weight, and the reason is usually that compressing in bulk was a pain, so nobody did it. Drop the whole folder in once, set the compression level, and the job takes a minute.

This batch compressor accepts jpg, jpeg, png and webp files of up to 20 MB each and optimises them all in one pass. You choose a compression level, either a sensible automatic setting or your own quality value, and every file is re-encoded on the server. The result panel shows the size of each original next to its compressed version, plus a running total, so you can see exactly how much bandwidth you just saved across the set.

Formats are preserved, so compressing a set of PNGs gives you PNGs and a set of JPGs gives you JPGs, with the correct extensions. That matters for bulk workflows where you are about to overwrite a directory of files: nothing gets renamed into a format the surrounding code does not expect, and transparency in PNGs and WebPs is kept. Download individually for a quick check, or take the whole optimised set as a ZIP ready to upload.
