BMP että PNG Usein kysytyt kysymykset konversioista
How do I convert a BMP image to PNG?
+
Drop your BMP 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 BMP 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 BMP to PNG converter keep transparency?
+
When PNG supports an alpha channel (PNG, WebP, GIF) and the original BMP 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 BMP 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 BMP to a raster PNG (or vice versa)?
+
Kyllä. Vektori-rasteri-muunnokset rasterisoivat järkevällä oletusresoluutiolla (tyypillisesti 2 x näyttö); voit ohittaa DPI:n valintapaneelissa. Rasteri-vektori on paras jäljitys ja toimii parhaiten logoissa ja linjataiteessa, ei valokuvissa.
What is the largest BMP 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 BMP images to PNG?
+
Yes — drag a folder of BMP 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 BMP?
+
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 BMP image private when I convert it?
+
Yes. Uploads are encrypted in transit, the conversion job runs on an isolated worker, and the original BMP plus the resulting PNG are deleted within an hour.
Why is my converted PNG file larger than the original BMP?
+
If PNG is lossless and BMP 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 BMP to PNG converter handle animated images?
+
If BMP is animated (GIF, WebP, APNG) and PNG also supports animation (GIF, WebP), all frames are preserved. Converting animated BMP to a static target (JPG, PNG) keeps only the first frame.
Can I convert BMP to PNG on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert BMP to PNG from any iPhone or Android device without using local storage.
