What is the difference between extracting images and converting PDF to JPG?
Extraction saves raster pictures stored inside the PDF without the surrounding page. PDF to JPG renders each complete page, including text, vectors, backgrounds, and images.
Does image extraction preserve the original quality?
Embedded JPEG and JPEG 2000 streams are copied without re-encoding. Pixel-only streams are losslessly packaged when necessary, although PDF-specific metadata may not become part of the standalone file.
Why did the tool find one image for an entire scanned page?
Many scanners store each page as one full-page raster image. In that case, extracting the embedded image naturally returns the complete scan.
Can I extract JPG and PNG images from a PDF?
Yes. Native JPEG and JPEG 2000 streams are preserved when possible. Pixel-only image streams that do not contain a complete standalone file are losslessly packaged as PNG.
Why were no images found in my PDF?
The visible content may consist entirely of text and vector graphics, use unsupported image masks or encodings, or be generated dynamically rather than stored as standalone raster images.
Can I download every extracted image together?
Yes. Choosing Extract Images creates and downloads one ZIP containing every supported embedded image.
Is my PDF uploaded?
No. PDF parsing, image extraction, and ZIP generation happen locally in your browser.
