JPEG i PNG Cwestiynau Cyffredin Trosi
How do I convert a JPEG image to PNG?
+
Drop your JPEG image into the upload area. PDF.to re-encodes the pixels into the PNG container and gives you the new file in seconds. No account is needed.
Will the JPEG to PNG conversion lose detail or sharpness?
+
If PNG is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If PNG 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 JPEG to PNG converter keep transparency?
+
When PNG supports an alpha channel (PNG, WebP, GIF) and the original JPEG 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 JPEG file?
+
ICC color profiles and DPI tags are preserved when PNG 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 JPEG to a raster PNG (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 JPEG image I can convert to PNG?
+
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 JPEG images to PNG?
+
Yes — drag a folder of JPEG files onto the page. Each is converted independently and zipped into a single download when done.
Will the converted PNG have the same dimensions as my JPEG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the PNG resize tool after the conversion finishes.
Is my JPEG image private when I convert it?
+
Yes. Uploads are encrypted in transit, the conversion job runs on an isolated worker, and the original JPEG plus the resulting PNG are deleted within an hour.
Why is my converted PNG file larger than the original JPEG?
+
If PNG is lossless and JPEG 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 JPEG to PNG converter handle animated images?
+
If JPEG is animated (GIF, WebP, APNG) and PNG also supports animation (GIF, WebP), all frames are preserved. Converting animated JPEG to a static target (JPG, PNG) keeps only the first frame.
Can I convert JPEG to PNG on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert JPEG to PNG from any iPhone or Android device without using local storage.
