What image formats does FlowPDF support for extraction?

FlowPDF extracts images in whatever format they were stored in the PDF. Common formats include JPEG (for photographs), PNG (for graphics with transparency), TIFF (for high-resolution scans), JPEG2000, and GIF. The tool doesn't convert them — it preserves the original file format. This means you get exactly what the document creator embedded, with no unnecessary transcoding.

Will extracted images have the same resolution as the original upload?

Yes — FlowPDF extracts the image objects as they exist in the PDF. If the creator embedded a 300 DPI, 4000×3000 pixel photograph, you get that exact image, not a downscaled version. PDFs often store images at high resolution for print purposes, and extraction gives you access to that full resolution, which is perfect for repurposing in other design tools or for high-quality printing.

Can I extract only specific images from a PDF, not all of them?

Yes — you can describe which images you want, either by page number or by description. For example, 'extract the image from page 3' or 'extract the company logo on page 1.' If you just say 'extract all images,' you get everything in a zip. If you need only some, FlowPDF can target them specifically.

What if the PDF contains images that are actually vector graphics?

Vector graphics in PDFs (like logos created from mathematical shapes rather than pixels) are not stored as image objects — they're stored as drawing instructions. extract-images pulls only raster images. If your document contains vector logos or diagrams that you need as editable vector files, you'd need a separate tool that handles vector extraction. However, many PDFs embed vector logos as a raster preview for display compatibility, and that raster version can be extracted.

Does extracting images remove them from the PDF or just copy them?

Extraction creates copies of the images as separate files. The original PDF remains untouched in your workspace. This means you get the images as standalone assets while keeping your PDF intact. If you actually want to remove images from the PDF (to reduce file size or create a text-only version), that's a different operation — you'd need to use a redaction or deletion tool to remove the images from the document itself.

Extract Images from PDF Online — Free, Original Quality, No Sign-Up

PDFs are surprisingly good at hiding high-quality images. You see a beautiful photograph or a crisp diagram on the page, but the moment you try to copy it — screenshot, right-click save, or screen grab — you lose resolution, introduce compression artifacts, and end up with a degraded mess. FlowPDF extracts the actual embedded images from your PDF at their original quality, preserving the exact resolution, color profile, and file format the creator embedded. This is fundamentally different from converting the entire page to an image — extraction reaches into the PDF's object structure, pulls out the original image objects, and delivers them as standalone files. You get JPEGs, PNGs, or whatever format the image was stored in, without any re-encoding or quality loss. This is essential for designers needing clean assets, researchers needing exact figures, or anyone building a presentation from a PDF source.

How it works

1
Upload your PDF.
2
Tell FlowPDF you want the images — for example, 'extract all images' or 'get me the photos from this document.'
3
FlowPDF scans the document, identifies all embedded images, and bundles them.
4
Download the zip containing every image in its original format and resolution.

Frequently asked questions

This is the most common point of confusion. pdf-to-jpg renders each entire page as an image — it's like taking a screenshot of the page. You get the full page layout, including text, backgrounds, and headers, but only at the resolution of the page render. extract-images pulls out the individual image objects that were embedded in the PDF — a photo, a logo, an illustration — at their original resolution and in their original file format (JPEG, PNG, TIFF, etc.). If you need a specific photo from a report, use extract-images. If you need a full page image, use pdf-to-jpg. The outputs serve completely different purposes.
