WebP to PNG converter
Convert a still WebP to PNG while retaining transparency in the decoded image. Inspect the alpha edges and file size; motion and lost detail are not recovered.
Keep alpha for your next composition
A WebP cutout or graphic can have fully transparent areas and soft semitransparent edges. PNG is a useful editing copy when the next application accepts PNG but not WebP. This workflow keeps alpha from the browser-decoded still image instead of placing the subject on a solid background. The checkerboard in the result is a preview aid, not a texture painted into the file. Download the PNG and place it on both a light and a dark background to inspect edge quality.
Lossless output is not recovered source detail
WebP may have been encoded lossily or losslessly before you received it. PNG can preserve the decoded image without a further lossy encoder, but cannot undo old texture loss or remove a colored halo that is already in the pixels. Fully transparent RGB values and color management are also not guaranteed to remain byte-for-byte identical through browser rendering. Keep the source file for archival work. If the image is already opaque, converting it to PNG does not manufacture a transparent background.
Use the copy for a specific editing need
PNG output can be larger than WebP, especially for photographs. That is not necessarily a conversion failure: the formats encode data differently. Check the destination's byte cap and whether the entire image is still needed before making another export. Queue up to 20 still images; processing runs one image at a time to limit memory use. Download ready results individually or as a ZIP. Animations and layered documents are not preserved. Inspect the downloaded result in the application where you will actually use it. If only JPEG is accepted, flatten separately using WebP to JPG and choose the background deliberately.

How it works
Choose your WebP images
Select or drop up to 20 still images, 10 MB each and 100 MB combined. Every file is checked; originals are not overwritten.
Review the transparency limits
PNG has no lossy quality control here. Animation and original metadata are not preserved.
Convert and inspect
Process the queue, then select a file to inspect its original or converted preview at fit size or 100%. Retry errors separately; successful results remain available.
Save ready files or a ZIP
Download files individually or package ready results as a real ZIP. Duplicate names receive a number. Save outputs before clearing the queue or leaving the page.
People use it for…
Transparent overlay
Carry the cutout into an editor that accepts PNG with alpha.
Static graphic reuse
Create a compatible copy without applying another lossy quality setting.
Supports
Privacy & security
The converter reads a local file and creates a local download. Optional site analytics follow your consent choice; no image upload is required.

No
Data retention
No automatic source or result saving; download the result before closing the tab.

- •Results and ZIP contents are limited to 100 MB per queue
- •Still images only: animation is not preserved
- •EXIF, ICC profiles, and print metadata are not preserved as an archival copy
- •No automatic backup, file-size promise, or upload-acceptance guarantee
Frequently asked.
No. It is the preview background. A transparent PNG has alpha pixels; open it over different colors to inspect them.
No. This is a still-image workflow. Use an animation-aware converter if the source has multiple frames you need to retain.
No. It avoids another lossy export but cannot restore information lost before conversion.
An opaque WebP stays opaque. Format conversion does not remove a background or create a subject mask.
Yes. Alpha, image complexity, and the compression method all affect bytes. A larger but valid editing copy can be the expected result.
No. Browser decoding and Canvas encoding create a rendered image copy, not an archival transcode of all original metadata and fully transparent RGB values.

WebP to PNG: Keep Alpha Without Promising New Detail
Convert a still WebP graphic into PNG for editing, inspect transparent edges correctly, and understand larger output files and animation limitations.
Preserve Transparency When Converting Image Files
Distinguish alpha from painted backgrounds, choose a format that keeps transparency, and check cutout edges without confusing the preview grid with pixels.
Image Conversion vs Compression: Solve the Right Problem
Separate file-format conversion, byte-size compression, and pixel resizing so you can meet an upload requirement without unnecessary quality loss.
