Frequently Asked Questions

Why convert PDF pages to uncompressed BMP format?

BMP format provides raw, uncompressed 24-bit pixel data ideal for legacy software and computer vision pipelines.

Does converting to BMP cause compression artifacts?

No, BMP is completely uncompressed, ensuring that every rendered pixel is preserved without JPEG compression noise.

Can I extract all pages of a multi-page document at once?

Yes, every page is processed and saved as an individual numbered bitmap file inside a single archive.

How large will the resulting BMP files be?

Because BMP stores raw pixel arrays, high-resolution pages will produce larger files than compressed JPEG formats.

Are confidential document pages uploaded to any remote server?

No, all page rasterization takes place entirely inside your web browser without sending data online.
