PNG to WebP Conversion FAQ
How do I convert a PNG image to WebP?
+
Drop your PNG image into the upload area. PDF.to re-encodes the pixels into the WebP container and gives you the new file in seconds. No account is needed.
Will the PNG to WebP conversion lose detail or sharpness?
+
If WebP is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If WebP is lossy (JPG, WebP, JPEG), we use a high default quality setting that is visually indistinguishable from the source for almost all images.
Does the PNG to WebP converter keep transparency?
+
When WebP supports an alpha channel (PNG, WebP, GIF) and the original PNG had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Does it preserve EXIF, color profile, and DPI from my PNG file?
+
ICC color profiles and DPI tags are preserved when WebP supports them. EXIF metadata (camera, GPS, timestamps) is stripped by default for privacy; turn it on in PRO if you need it.
Can I convert a vector PNG to a raster WebP (or vice versa)?
+
Yes. Vector-to-raster conversions rasterize at a sensible default resolution (typically 2× display); you can override the DPI in the options panel. Raster-to-vector is best-effort tracing and works best on logos and line art, not photographs.
What is the largest PNG image I can convert to WebP?
+
Free accounts: up to 100 MB or 50 megapixels per image. PRO accounts: up to 5 GB and 1 gigapixel per image, which covers large scans and panoramas.
Can I batch-convert PNG images to WebP?
+
Yes — drag a folder of PNG files onto the page. Each is converted independently and zipped into a single download when done.
Will the converted WebP have the same dimensions as my PNG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the WebP resize tool after the conversion finishes.
Is my PNG image private when I convert it?
+
Yes. Uploads are encrypted in transit, the conversion job runs on an isolated worker, and the original PNG plus the resulting WebP are deleted within an hour.
Why is my converted WebP file larger than the original PNG?
+
If WebP is lossless and PNG was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Does the PNG to WebP converter handle animated images?
+
If PNG is animated (GIF, WebP, APNG) and WebP also supports animation (GIF, WebP), all frames are preserved. Converting animated PNG to a static target (JPG, PNG) keeps only the first frame.
Can I convert PNG to WebP on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert PNG to WebP from any iPhone or Android device without using local storage.
