How do I convert a PDF file to SRF online?

Upload your PDF file, choose target format SRF, select desired DPI (72, 150, 300) to control raster resolution, then click Convert. Our server renders each PDF page as a high-quality SRF raster image, which you can download individually or as a ZIP archive. No software installation is required.

Why would someone convert PDF to SRF instead of keeping the PDF?

PDF is a vector-based document format, while SRF is a raster image format used in specialized imaging pipelines. Converting PDF to SRF rasterizes text and graphics into a fixed pixel grid, which is required by many archival systems, scientific publishing platforms, and imaging software that cannot parse PDF. It also lets you control output resolution precisely and strip away interactive elements such as links or form fields.

What happens to color profiles, vector layers, and transparency when converting PDF to SRF?

During PDF to SRF conversion, vector entities are rasterized at the chosen DPI, so lines and text become pixel-based without any loss in sharpness if the DPI is high enough. Color profiles embedded in the PDF (like CMYK or sRGB) are preserved in the SRF metadata where the format supports it. However, layers and interactive objects from PDF cannot be retained because SRF is a flattened raster format. Transparency is handled depending on the SRF variant; if the target SRF format does not support alpha channels, transparent areas are composited onto a white background.
