A 700 KB WebP typically becomes 1.5 – 3 MB as PNG.
Quality: Lossless conversion (if the source is lossless WebP) or re-encoded once at higher fidelity (if the source is lossy WebP).
Best for: editing in design software that doesn't support WebP, archival.
Avoid when: you only need the image for web display.
Tip: PNG preserves WebP's transparency. Pick PNG only if your downstream tool requires it.
About the output format
When PNG is the right output
PNG is lossless and supports transparency — the two things JPG can't do. Screenshots, UI mockups, logos, icons, diagrams, and anything with sharp edges or text should be PNG. File sizes are larger than JPG for photographic content (usually 2-5×), so PNG is a bad choice for photographs unless you specifically need lossless. Note: PNG has no metadata for camera EXIF, so converting a photo JPG → PNG loses the camera info.
WebP to PNG: preserving what matters
If the WebP was encoded with lossy VP8 compression, converting to PNG wraps the decoded pixels losslessly — no further quality loss, but no improvement either. If the WebP used VP8L (lossless), the PNG is a true lossless-to-lossless transfer. The critical difference: PNG preserves alpha-channel transparency that JPG would destroy. For WebP images with transparent backgrounds (logos, icons, product cutouts), PNG is the correct conversion target, not JPG.
When to convert WEBP to PNG
Choose PNG over JPG when the WebP has transparency, when the image is a screenshot or graphic with sharp edges (PNG handles these better than JPG), or when your workflow requires lossless output for further editing.

About the WebP Format
WebP is a modern image format developed by Google in 2010, based on the VP8 video codec. It supports both lossy and lossless compression modes, giving developers and designers flexibility to choose the right balance between quality and file size. WebP images are typically 25-35% smaller than equivalent-quality JPEG files, making it a compelling choice for web performance optimization.
WebP excels in web environments where bandwidth and loading speed are critical. It combines features that previously required multiple formats — lossy compression like JPEG, transparency like PNG, and animation like GIF — all in a single format. With over 97% browser coverage across Chrome, Firefox, Safari, and Edge, WebP has become one of the most practical choices for modern web development. Its primary limitation is reduced support in older desktop software and some native image editors.
WEBP to PNG FAQ
Quick answers about compatibility, quality, metadata handling, and the most common reasons to convert WEBP files to PNG.
How do I convert WEBP to PNG online?
Upload your WEBP image to iFormat and click Convert — it's decoded and re-encoded to PNG in seconds. It's free, adds no watermark, and needs no account. Batch upload is supported, and results download individually or as a ZIP.
Can I convert WEBP to PNG without losing quality?
PNG is a lossless format with transparency support. When PNG is lossless (PNG, TIFF, BMP), every pixel is preserved exactly. When it's lossy (JPG, WebP), iFormat uses a high default quality so the difference is invisible at normal viewing size. For the sharpest result, always convert from the highest-quality source you have.
How to batch convert WEBP files to PNG for free
Upload multiple WEBP files at once — iFormat converts them all to PNG in one batch. Each result downloads individually or as a single ZIP. No sign-up, no watermark, and no per-file limit on the free plan beyond the 50 MB per-file cap.
Does converting WEBP to PNG keep transparency?
If both formats support an alpha channel (PNG, WebP, GIF, TIFF), transparency carries over. When the target lacks transparency (like JPG), transparent areas are flattened onto a solid background rather than lost silently — preview the result before you rely on it.
Can I convert WEBP to PNG on my phone without installing an app?
Yes. iFormat runs entirely in your browser on iPhone, Android, iPad, or any mobile device — no app download needed. Upload your WEBP photo, tap Convert, and save the PNG directly to your camera roll or files.
WEBP vs PNG — which format should I use?
WEBP is a modern Google format with strong compression best for fast-loading web images. PNG is a lossless format with transparency support best for logos, screenshots, and graphics with sharp edges. Use PNG when a website, form, or app requires it, or when you need PNG's specific strengths like smaller file size, wider compatibility, or transparency support.
Is it safe to convert WEBP to PNG online?
Yes. Uploads travel over an encrypted HTTPS connection, conversion runs on an isolated worker, and both your WEBP source and the PNG result are automatically deleted from our servers within a short window. Nothing is stored, shared, or used for training.
Is there a file size limit for WEBP to PNG conversion?
The free plan supports files up to 50 MB, which covers the large majority of WEBP files. For longer or higher-resolution files, Starter raises the limit to 100 MB, Plus to 1 GB, and Pro to 5 GB.
When should I convert WebP to PNG instead of JPG?
Three situations: (1) the WebP has transparency you need to preserve — PNG supports alpha channels while JPG does not; (2) the image is a screenshot, diagram, or graphic with sharp text where lossless quality matters; (3) your workflow requires pixel-perfect fidelity with no compression artifacts.
Will the PNG file be much larger than the WebP?
For photographs, typically 3–8× larger. For screenshots and graphics with flat colors, PNG may be only 20–50% larger since PNG compresses that type of content efficiently.
