PDF to Image under a size limit

To convert a PDF to images under a size limit, drop the PDF on the tool, pick JPG, PNG, or WebP, choose the largest size one image may be, and download the ZIP. pdfly draws each page, saves it in that format, and checks the size of that real file. Every image in the ZIP is at or under the size you chose.

1. Drop one PDF on the tool, or browse for it. It can be up to 100 MB and 100 pages.
2. Pick the image format. JPG opens selected because nearly every form accepts it.
3. Pick a size per image. 200 KB opens selected because many upload forms accept it. Choose Custom for any other number.
4. Start the conversion. A short line tells you how many images were made and the size limit they meet.
5. Download one ZIP with one image per page.

JPG is the safe choice. Every upload form, email client, and phone opens it, and it handles scans and photos well. Its compression is lossy, so at small sizes you may see soft edges around text, but a page stays readable down to a surprisingly small file.

PNG is lossless: text, lines, charts, and diagrams come out exactly as drawn, with no smudges around letters. That makes it the best fit for slides, forms, and pages that are mostly text on a plain background. The cost is size. A page full of photos can be several times larger as a PNG, so give it a bigger limit. When the full-color file is too big, pdfly tries again with 256 colors, which most text pages cannot tell apart, before it lowers the resolution.

WebP is a newer format from the web. At the same size it usually looks sharper than JPG, so it is a good pick when a site or app takes it. Some older portals and desktop programs still refuse it; if the form lists only JPG and PNG, use one of those.

Many forms ask for a page of a document as an image, not as a PDF, and they cap that image at a fixed size. A converter that only exports pages gives you files of whatever size they happen to be. A page with a photo on it can easily be a few megabytes, and you are left to find an image compressor and guess a setting for each file.

Here the size is part of the job. pdfly measures each image it writes and keeps the best version that fits. You do not have to try settings one by one, and an image over your limit is never handed out.

Each page is drawn once at 150 DPI, with smooth edges on text and lines. That is sharp on a phone or laptop screen and close to what most forms expect from a scan. For JPG and WebP, pdfly then looks for the highest quality whose file is still under your size, so a page with room to spare stays as clear as it can be. PNG has no quality setting, so pdfly keeps every color when it fits and drops to 256 colors when it does not.

When even the smallest version pdfly allows is still too big, the image is made smaller in steps and the search runs again at each step. Small text gets softer at low resolutions, so if a page comes back hard to read, pick a larger size. If one page cannot get under your size at all, you get a message with the page number and the smallest size it reached, and no ZIP.

The images are named after your PDF, followed by the page number, and the format's extension, such as report-page-01.jpg, report-page-02.jpg, or report-page-01.png. The numbers are padded with zeros so the files sort in page order in any folder. A one-page PDF still comes as a ZIP, so every conversion downloads the same way.

To convert only some pages, or to fix pages that are upside down first, reorder, rotate, or delete pages, download that PDF, and convert it here. Rotation is kept, so a page you turned upright becomes an upright image.

A scanned PDF is already a set of images, one per page, and it converts the same way. pdfly draws the page as it looks, so stamps, signatures, and handwriting all appear in the image. JPG or WebP is usually the better fit for scans, since PNG files of scanned paper grow large. Scans are often large, which is exactly where a size limit helps: the image is brought under your number without a separate step.

If the portal wants one PDF rather than images, you do not need to convert at all. Use the PDF compressor instead, or split the PDF by size when it takes several smaller files.

After editing or cropping the images, you may need a PDF again. The JPG to PDF tool puts each image on its own page in the order you set and keeps that PDF under a size you choose. You can turn JPG images into a PDF with the same kind of size limit.

One conversion takes one PDF up to 100 MB and 100 pages. Password-protected PDFs are not accepted; remove the password first. The size per image can be anything from 8 KB to 100 MB. The output is JPG, PNG, or WebP, one format per conversion. The upload and the ZIP are deleted within 1 hour, and there is no account to create.
