PNG i JPEG Cwestiynau Cyffredin Trosi
How do I convert a PNG image to JPEG?
+
Drop your PNG image into the upload area. PDF.to re-encodes the pixels into the JPEG container and gives you the new file in seconds. No account is needed.
Will the PNG to JPEG conversion lose detail or sharpness?
+
If JPEG is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If JPEG 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 JPEG converter keep transparency?
+
When JPEG 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 JPEG 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 JPEG (or vice versa)?
+
Ie. Mae trawsnewidiadau fector-i-raster yn rastereiddio gyda chysylltiad rhagosodedig rhesymol (defnyddio dangosydd 2x yn aml); gallwch drosysgrifo'r DPI yn y panel dewisiadau. Tracio ymdrech orau yw raster-i-fector ac mae'n gweithio orau ar logo a lluniau llinell, nid ffotograffau.
What is the largest PNG image I can convert to JPEG?
+
Free accounts allow images up to the free size limit. PRO accounts allow much larger images and up to 1 gigapixel per image, which covers large scans and panoramas.
Can I batch-convert PNG images to JPEG?
+
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 JPEG have the same dimensions as my PNG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the JPEG 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 JPEG are deleted within an hour.
Why is my converted JPEG file larger than the original PNG?
+
If JPEG 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 JPEG converter handle animated images?
+
If PNG is animated (GIF, WebP, APNG) and JPEG 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 JPEG on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert PNG to JPEG from any iPhone or Android device without using local storage.
