Why convert WebP to PNG?
WebP is Google''s modern web image format — efficient, widely supported in browsers, but still not natively handled by many desktop applications. Photoshop (pre-2022 versions), older Illustrator, Windows Photo Viewer on older builds, many CMS platforms, and legacy print workflows all need PNG or JPEG. Converting WebP to PNG gives you the universal lossless format that every design tool and application accepts without plugins or workarounds.
PNG is specifically the right target when the WebP source has transparency — a transparent background for a logo, a product cutout, a UI element with alpha. JPG cannot store transparency; PNG can. For web asset pipelines, game assets, and UI design systems, PNG is the standard interchange format.
Developers who download web resources, marketers who receive creative assets, and designers who work with downloaded reference imagery all regularly encounter WebP files. Converting them to PNG unlocks the files for use in the full range of desktop tools and internal platforms.
File Converter Pro converts WebP to PNG entirely offline on Windows 10 and 11. No upload, no browser extension required, no online tool needed — just drag and convert.
How to convert WebP to PNG on Windows
- Install File Converter Pro. Download File Converter Pro from the Microsoft Store. The free trial supports WebP to PNG conversion at full resolution.
- Drag WebP files into the queue. Drop one WebP file, a multi-select, or an entire folder into the app. Lossy WebP and lossless WebP files are both handled.
- Select PNG as output. Choose PNG in the output panel. PNG-24 with alpha channel is the default, preserving any transparency in the WebP source.
- Convert locally. Click Convert. Output PNGs are saved to your chosen folder. Transparency is carried over automatically.
Batch conversion for big folders
Web asset libraries, downloaded design kits, and scraped image collections often consist entirely of WebP files. File Converter Pro processes these batches efficiently.
- Convert entire folders of WebP assets in one run.
- Transparency (alpha channel) preserved in every output PNG automatically.
- Filenames retained with .png extension substituted.
- Works offline in isolated networks — no outbound connections needed.
Quality settings that actually matter
PNG output is lossless — no quality slider reduces pixel fidelity. The only tunable parameter is compression level, which affects file size and encode speed but never visual quality:
- Compression 6 (default): excellent balance of file size and speed for all use cases.
- Compression 9: smallest file, slowest encode. Best when output PNGs will be served on a website.
- Compression 0: fastest encode, largest file. For intermediate files in a fast pipeline.
- Lossless WebP input: when the source is lossless WebP, the PNG output is a true lossless copy of the original pixels.
Common issues and fixes
- PNG is much larger than the WebP. Expected — WebP uses efficient lossy or lossless compression; PNG lossless files are larger by nature. For web delivery keep using WebP; use PNG for editing and tool compatibility.
- Animated WebP only converts first frame. For animated WebP, only the first frame is extracted as a static PNG. Convert to GIF or WebM for animated output.
- Transparency missing in output. Ensure PNG-24 (not PNG-8) is selected. PNG-8 does not support a full alpha channel — only binary transparency at a palette level.
- Colour looks slightly different. Lossy WebP may encode colour differently from the original. PNG output faithfully represents what the WebP contains — any colour shift was in the WebP encoding step, not in the PNG conversion.

FAQ
Does converting WebP to PNG preserve transparency?
Yes. WebP supports alpha channels and File Converter Pro carries transparency to the PNG alpha channel. Select PNG-24 (not PNG-8) for full alpha support.
Is the PNG output lossless even if the source WebP was lossy?
The PNG output is a lossless snapshot of the WebP image data. If the WebP was lossy, any compression artefacts that were already in the WebP are preserved faithfully in PNG — but no additional quality loss occurs in conversion.
Can I convert an entire folder of WebP files to PNG?
Yes. Drop the folder into File Converter Pro and all WebP files are converted in one batch run with no file count limit.
Why are my output PNG files so much larger than the WebP originals?
WebP uses very efficient compression (lossy or lossless). PNG lossless files are larger — this is expected. For web delivery, keep using WebP. Use PNG when you need the file for editing in desktop software.
