Learn about the characteristics of common bitmap formats to choose the right output:
| Format | Characteristics | Best For |
|---|---|---|
| BMP | Lossless, uncompressed, true-to-life colors, large file size | Image editing, printing and other quality-critical scenarios |

| PNG | Lossless compression, supports transparency, moderate size | Web design, icon creation |
FAQ
It is an online tool that exports every page of a PDF document as a BMP bitmap image. It supports high, medium, and low quality, with the option to merge pages into one long image or export each page separately — all processed locally in your browser without uploading files.
Upload a PDF file, choose the image quality and output mode, then click "Start Process" to download. Batch upload and pack download are supported.
It depends on the output mode you choose. With "Each page as separate BMP", every page of the PDF is exported as an independent BMP image and packed for download; with "All pages in one BMP", all pages are stitched into a single image.
High quality offers higher resolution (about 150 DPI) with clearer images and larger files; low quality has lower resolution and smaller files. For general document viewing, "Medium" is usually enough.
Yes. Scanned PDFs are themselves made of images, so converting to BMP preserves the page images as-is without a second loss of quality.
BMP is an uncompressed lossless bitmap format that saves every pixel, so the file size is significantly larger than JPG/PNG. If size matters, use the PDF to JPG/PNG tool instead.
BMP is lossless but large; JPG is lossy, small, and good for photos; PNG is lossless, supports transparency, and moderately sized. Choose the format that fits your purpose.
Batch upload and conversion are supported. Multiple PDF files can be processed simultaneously; regular-sized files are fully supported, while very large files are best processed in batches, and members enjoy higher limits.
Conversion happens in real time in your browser and is quite fast. Processing speed depends on the number of pages, resolution, and your device performance — no waiting in a server queue.
Completely secure. All processing is done locally in your browser — PDF files are never uploaded to any server, and your data always stays on your device.
Free usage is granted every day, so daily use costs nothing. No registration is required; when you need higher processing volume, upgrading to membership unlocks more benefits.
Check that your PDF is not corrupted or encrypted, and try lowering the image quality. If pages look blurry due to low resolution, re-convert with the "High" quality setting.
