How to Convert WebP to PNG
To convert WebP to PNG, upload the WebP file above, select PNG, and download a universally compatible, lossless copy. This is the right move when an app, editor, or upload form refuses WebP files — PNG opens absolutely everywhere, and transparency carries over intact.

JoltFile desktop appHow to convert WebP to PNG in 5 steps
The whole process takes under two minutes and requires no software installation or account. Your original WebP file is never modified.
Upload your WebP file
Drag your .webp file onto the converter above, or click “Browse files” to select it from your device. Files are processed locally in your browser whenever possible — nothing is uploaded to a server.
Confirm the output format is PNG
The converter defaults to WebP → PNG on this page. If you dropped in a different file type, set the target format to PNG (.png) using the format menu.
Adjust quality settings
Choose your quality settings. For photos, quality 90 is visually indistinguishable from the original; graphics with text or transparency should use the lossless option when available.
Convert the file
Click “Convert”. JoltFile processes the file and shows a progress indicator — most image conversions finish in a few seconds.
Download your PNG file
Save the converted .png file to your device. The original WebP file is never modified, and temporary data is discarded automatically.
What happens to quality when converting WebP to PNG?
If the source WebP was lossless, the PNG is pixel-identical. If it was lossy, the PNG preserves its current state exactly (no new loss) — but file size will grow, often 2–5×, because PNG's lossless compression is less efficient than WebP's.
When should you convert WebP to PNG?
- Opening WebP files in older editors that don't support the format
- Uploading images to forms or CMSs that reject .webp
- Editing a WebP image repeatedly without compounding loss
- Printing, where PNG/TIFF workflows are the norm

About the WebP and PNG formats
What is WebP? (Web Picture format)
WebP is a modern image format developed by Google in 2010 that supports both lossy and lossless compression, transparency, and animation in a single container. Google reports WebP lossy files are typically 25–34% smaller than comparable JPEGs, and lossless files about 26% smaller than PNGs.
Strengths
- 25–34% smaller than JPEG at equivalent quality (per Google)
- Supports transparency AND animation in one format
- Supported by all modern browsers since ~2020
- Both lossy and lossless modes
Limitations
- Older software (legacy editors, some CMSs) may not open it
- Not accepted by every print or desktop publishing workflow
- Encoding is slower than JPEG
What is PNG? (Portable Network Graphics)
PNG is a lossless raster image format created in 1996 as a patent-free replacement for GIF. It supports full alpha transparency and compresses without discarding any pixel data, which makes it the default choice for screenshots, UI assets, logos, and graphics with sharp edges or text.
Strengths
- Lossless compression — pixels survive every save
- Full alpha-channel transparency
- Universal support in browsers, editors, and operating systems
- Ideal for text, line art, and screenshots
Limitations
- Files are much larger than JPEG or WebP for photographs
- No native animation support (APNG exists but is a separate spec)
- No embedded color-management or metadata richness compared to TIFF
WebP to PNG conversion: your questions answered
Does converting WebP to PNG lose quality?
No. PNG is lossless, so the conversion preserves the WebP's current pixels exactly — including any loss already present in a lossy WebP. Nothing new is discarded.
Why would I convert WebP to PNG if WebP is smaller?
Compatibility. Some desktop editors, upload forms, office suites, and older devices still refuse WebP. PNG is the format everything accepts.
Will transparency survive the conversion?
Yes. Both formats support full alpha transparency, and it carries over perfectly.
Is it free to convert WebP to PNG with JoltFile?
Yes. JoltFile's free tier covers everyday WebP to PNG conversions with no account and no watermarks. Higher file-size limits and batch processing are planned for the upcoming Pro tier.
Is my WebP file private when I convert it?
Yes. JoltFile is designed around browser-based processing: whenever technically possible your file is converted locally on your own device and never uploaded to a server. Files that do require server processing are encrypted in transit and deleted automatically after conversion.
