PNG to ZIP Optimization FAQ

Will the ZIP compress my PNG files much?

It depends on the content. Already-compressed PNG files (most video, audio, JPG, PNG) shrink very little inside a ZIP — the archive mainly bundles them. Text, documents, and uncompressed data compress substantially. Either way you get one convenient file.

Can I add many PNG files to a single ZIP?

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

What can open the ZIP after I download it?

Standard archive tools open a ZIP everywhere: built-in extractors on Windows and macOS, plus 7-Zip, WinRAR, The Unarchiver, and the unzip command line. No special software is needed to get your PNG files back out.

Does putting my PNG in a ZIP change the files inside?

No — archiving is lossless. Your PNG files come back out of the ZIP byte-for-byte identical; nothing is re-encoded or degraded. The archive is just a container.

How long does building the ZIP take?

It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.

Is my PNG data private while the ZIP is built?

Yes. Uploaded PNG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted ZIP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

Will the ZIP keep my folder structure?

Can I convert a PNG to a ZIP on my phone?

Yes — the upload-then-download flow works on mobile browsers, and the resulting ZIP saves to your device. Use a file manager app to extract the PNG files back out afterward.

PNG

PNG files cater to transparency and use lossless compression, making them ideal for graphics, logos, and screenshots.

ZIP

ZIP is a widely used compression and archive format. ZIP files group assorted files and folders into a single compressed file, reducing storage space and facilitating easier distribution. They are commonly used for file compression and data archiving.
