PNG files are also easily viewable on all web browsers. Generally, PNG files will open in your operating system’s default image viewer. The benefits of using PNG are Plus, PNG is an open format that uses lossless compression. PNG also supports animations with better transparency (try our GIF to APNG). PNG images can have RGB or RGBA colors and support transparency, which makes them perfect for use in icons, or graphic designs. Portable Network Graphics (PNG) is a raster-based file type that compresses images for portability. I highly recommend SumatraPDF or MuPDF if you're after something a bit more. You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. Most web browsers, like both Chrome and Firefox, can open PDFs themselves. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. Most people head right to Adobe Acrobat Reader when they need to open a PDF. PDF files always look identical on any device or operating system. The reason PDF is so widely popular is that it can preserve original document formatting. You can't get higher quality than that.The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today. The extracted JPEGs were byte-for-byte identical to I tried this command on a PDF that I had made myself from a sequence (depending on what bitmap format the PDF was using). You may or may not need to follow that with a convert to. By default, pdfimages convertsĮverything to PNM format, and converting JPEG > PPM > JPEG is a lossy Probably also want to use the -j option to pdfimages, because a Them, because it gets you the raw data at its original size. Series of bitmaps, pdfimages will do a much better job of extracting It simply ignores any text or vectorĪs a result, if what you have is a PDF that's just a wrapper around a Pdfimages looks through the PDF for embedded bitmap images andĮxports each one to a file. pdfimagesĭoes not do the same thing that convert does when given a PDF asĬonvert takes the PDF, renders it at some resolution, and uses the Update: As you pointed out, gscan2pdf (the way you're using it) is just a wrapper for pdfimages (from poppler). (You can prepend -units PixelsPerInch or -units Perhaps you need to use -density to do the conversion at a higherĭpi: convert -density 300 file.pdf page_%04d.jpg Versions (as a PNG to avoid further quality loss). Perhaps cut the same section out of the poor quality and good quality Could you post some samples to illustrate? It's not clear what you mean by "quality loss". TLDR - Use pdfimages : pdfimages -j input.pdf output The method in the answer given here results in an output which is comparable in size to the input and doesn't suffer from quality loss. The currently accepted answer does the job but results in an output which is larger in size and suffers from quality loss. For example: pdftoppm input.pdf outputname -png -rx 300 -ry 300 Converting a single page or a range of pages of the PDF pdftoppm input.pdf outputname -png -f. This will output each page in the PDF using the format outputname-01.png, with 01 being the index of the page. You can use pdftoppm from the poppler-utils package to convert a PDF to a PNG: pdftoppm input.pdf outputname -png
