Turn PDF pages into JPG or PNG images. Nothing is uploaded.
PNG is the format to pick when a page has to stay crisp: contracts with small print, slides with thin lines, charts, screenshots saved as PDF, and pages with text you will crop or zoom into. A JPEG saves space by blurring fine detail, which shows up as faint smudges around letters. A PNG keeps every pixel, so edges stay clean. The price is size. An A4 page at 150 DPI is 1240 by 1754 pixels, and at 300 DPI it is 2480 by 3508 pixels, about 8.7 million pixels. A PNG of a text page is usually modest, but a page that holds photos or a scan can be many megabytes, and the Done list shows the true size of every file before you download. This page opens with PNG already selected for this visit, and it does not change the format you saved on the PDF to JPG page. Pages are drawn on a white background, so you will not get transparency. If you need smaller files, switch the format to JPEG or choose 150 DPI.
A PDF page has a size in points, and DPI says how many pixels to draw for each inch of it. An A4 page at 72 DPI becomes 595 by 842 pixels, which is enough for a small preview. At 150 DPI, the default, it becomes 1240 by 1754 pixels, which reads well on a screen and fits a slide or a web page. At 300 DPI it becomes 2480 by 3508 pixels, about 8.7 million pixels, which is what you want when the image will be printed or when you need to zoom into small text. Higher DPI means a bigger picture and a bigger file, so start at 150 and go up only if the result is too soft for your use. The live line above the button shows the pixel size before you convert.
JPEG throws away fine detail to make a small file. On photographs and scans that is hard to see, and the quality slider (50 to 100, default 90) lets you trade size against detail. On pages of text, charts or screenshots, a low quality leaves faint smudges around the letters. PNG keeps every pixel exactly, so text and lines stay sharp, but the files are larger, and at 300 DPI a full page can be very large. Both formats are saved on a white background, because a PDF page is opaque and JPEG cannot hold transparency anyway. This tool does not produce transparent backgrounds. Choose JPG for photo-heavy pages you will share or upload, and PNG for text and diagrams you want to keep crisp.
A browser can only draw a canvas up to a certain size, and the limit depends on the device. This tool respects about 16.8 million pixels per image on iPhone and iPad, 64 million pixels on other devices, and 16,384 pixels on the longest side. A 1000 by 1000 point page at 300 DPI would need 4167 by 4167 pixels, which is over the iPhone and iPad limit, so it is drawn at 4096 by 4096 pixels instead, which is about 295 DPI. The tool tells you before you convert which pages are affected and what resolution they will get, and the finished row says it again. Nothing is shrunk silently. On a phone, a run whose pages add up to more than 400 million pixels is blocked, and you are asked to choose fewer pages or a lower resolution.
The PDF is opened and drawn by code running in this tab. There is no upload step and no server that receives your pages. The page counts visits with Google Analytics, using rough groups such as 1 to 10 MB, never a file name, a page or an exact size. Pages are drawn one at a time, and each is released from memory as soon as its image is saved. A PDF over 200 MB or over 1000 pages asks you to confirm before it loads. This tool converts one PDF at a time. It does not remove a password, extract the pictures embedded in a PDF, or read text from scanned pages.
Usually yes for sharpness. Letters and lines keep clean edges in PNG, while JPEG at a low quality adds smudges around them. The cost is file size, so check the size of each row in the result and switch to JPEG at quality 90 if the PNGs are too heavy.
No. Each page is drawn on white, the way it prints, so the PNG is opaque. This tool has no option for transparent backgrounds. If you need to remove the white, do it in an image editor after converting.
The image is 2480 by 3508 pixels for A4. The file size depends on the page: a mostly white page of text is small, while a full-page photo or scan can be several megabytes. The result row shows the real size, not an estimate.
150 DPI suits most uses: an A4 page comes out at 1240 by 1754 pixels, which is clear on a screen and in a slide. Use 300 DPI (2480 by 3508 pixels) for printing or for zooming into small text, and 72 DPI (595 by 842 pixels) for thumbnails and quick previews.
Yes. Choose Page range and type pages such as 1-3, 5, 8-10. A range of 5-6 from a 12-page file gives report-page-005.jpg and report-page-006.jpg, so the numbers in the names match the PDF. One page gives a single image, and several pages give a zip.
PNG stores every pixel without losing any detail, and a page at 300 DPI has about 8.7 million pixels. A page full of photos or a scan can run to many megabytes. Switch to JPEG, or drop to 150 DPI, if the size matters more than perfect edges.
That page needs more pixels than this device can draw in one canvas, about 16.8 million on iPhone and iPad and 64 million elsewhere. The tool draws it as large as the device allows, for example 4096 by 4096 pixels instead of 4167 by 4167, and says which pages and which DPI before and after you convert.
Yes, in a current browser. Phones have less memory, so the limits are tighter: a run is blocked above 400 million pixels in total, and a PDF over 200 MB asks for confirmation. If a conversion fails, try 150 DPI or fewer pages.
No. The PDF is drawn in your browser tab and the images are made there too, so no page leaves your device. The site counts visits with Google Analytics using rough size groups, never a file name or a page.
