Add the batch
Open the converter, then select multiple files or drop the whole folder onto the drop zone. Every file is decoded locally and queued with its name shown in the list.
Batch conversion guide
Convert multiple WebP files to PNG at once — batch + ZIP
One WebP file is easy to convert. Fifty of them, dumped into a folder by a website export, a CMS migration, or a designer handoff, is where one-at-a-time converters die. PNGToolbox converts the entire batch in a single pass and hands you one ZIP archive: select your files, choose PNG or JPG output, and download. Everything runs in your browser, so there is no upload queue and no file-count server limit.
When you'll need it
Typical batch scenarios
Website exportsPlatforms and page-speed tools export images as WebP. Convert the whole export folder to PNG before you edit, archive, or re-upload it.
CMS and marketplace uploadsMany editors, marketplaces, and legacy upload forms reject WebP. A batch conversion keeps a products folder ready in the format the platform accepts.
Designer handoffsPNG is the safe interchange format for design work: lossless and readable by every tool. Convert a client's WebP set once, then share clean PNGs.
Long-term archivingPNG is a lossless format with broad support, which makes it a reasonable archival target when you want exact pixels and no recompression risk.
How it works
Three steps for the whole folder
Pick the output
Choose PNG for lossless output that keeps transparency, or JPG with an adjustable quality slider when you want smaller files. Optionally set an output size — useful when a whole set must share one resolution.
Convert and download
Start the conversion: each file is processed in your browser and measured. Download the whole set as a single ZIP, or grab individual PNGs from the result report.
Output choice
PNG or JPG for the batch?
Choose PNGWhen files contain text, logos, screenshots, or transparency — or when the destination accepts any format and you want lossless quality. Output keeps an alpha channel and every pixel exact.
Choose JPGWhen the batch is photographic and size matters: product photos, blog images, gallery shots. Quality 85 is a good starting point — big savings, little visible loss. Transparent areas become white.
Questions
Batch conversion FAQ
How many WebP files can I convert at once?
There is no artificial limit. Select or drop as many files as you need — very large batches process slower on low-memory devices, but nothing is uploaded or queued on a server.
Do converted files keep their original names?
Yes — each output keeps its source filename with the extension changed to .png, so a batch of photo-1.webp, photo-2.webp, ... becomes photo-1.png, photo-2.png, ... in the ZIP.
Will PNG conversion keep my transparency?
Yes. Transparent pixels in the WebP source are preserved in the PNG output. If you convert to JPG instead, transparency is filled with white because JPG cannot store an alpha channel.
Why are my WebP files being converted to larger PNGs?
PNG is lossless: it stores every pixel exactly, while WebP compresses more aggressively. Larger file size is the normal price of lossless, universally compatible output.
Are my files uploaded while converting?
No. Decoding, conversion, and ZIP packaging all run locally in your browser. Your files never leave your device.
Ready to convert the whole folder?
Batch conversion runs locally in your browser — free, no uploads, no limits.
