About this tool
Convert WebP images to high-quality PNG, JPG, or PDF files quickly in your browser. Batch convert multiple files and download as a ZIP archive.
WebP to PNG / JPG Converter decodes .webp files with your browser's own image decoder, redraws them on a canvas at their native pixel dimensions, and re-encodes them as lossless PNG, JPEG at a quality you set, or a single-page PDF sized to the image. Drop in a batch and it converts them all, then packages the results as a ZIP. It is for anyone stuck with WebP downloads that an older app, a print shop, a CMS or a client's template refuses to open.
Open WebP to PNG / JPG Converter on AltFTool — it loads instantly in your browser.
Upload or drag in the file you want to work with.
Adjust the settings and preview the result.
Download the finished file to your device.
The canvas is created at the image's naturalWidth and naturalHeight, so a 3000-pixel WebP comes out as a 3000-pixel PNG or JPG with no downsampling.
Convert a whole folder of WebP files in one pass and download them together rather than clicking through a save dialog per file.
The PDF is built with the page dimensions set to the image's pixel size and orientation chosen from its aspect ratio, so nothing is letterboxed onto A4 or letter.
PNG if the image has transparency or is a screenshot, logo, or line art, because PNG is lossless and keeps the alpha channel. JPG if it is a photograph and file size matters — JPEG has no alpha channel at all, so any transparent areas get flattened during conversion.
Converting to PNG does not add any loss, because PNG is lossless — though it cannot recover detail the original WebP already discarded. Converting to JPG re-encodes with lossy compression at the quality you choose (90 by default), which is visually near-transparent for photos but should not be repeated over and over on the same image.
Yes — add as many .webp files as you like, convert them in one run, and when more than one PNG or JPG is ready they are bundled into a single ZIP for download. PDF output is produced one file per image rather than zipped.
The PDF page is capped at 14,400 pixels on each side; anything larger is scaled down proportionally to fit before the image is embedded. The image is embedded as JPEG at the quality slider's setting, so lower the quality if the resulting PDF is bigger than you need.
