JPG to PDF under a size limit

To convert JPG images to a PDF under a size limit, add the images, put them in order, choose the largest size the PDF may be, and download it. pdfly places each image on its own page, then checks the size. If the PDF is already under your limit, you get it as it is. If it is over, the images are recompressed until it fits, and you still get one file.

1. Drop 1 to 20 JPG or PNG images on the tool, or browse for them. You can add more later.
2. Use the arrows to set the order. The first image in the list becomes the first page.
3. Pick a size. 1 MB opens selected because many forms accept it. Choose Custom for any other number.
4. Start the conversion and download one PDF.

A photo straight from a phone camera often weighs several megabytes. A few of them in one PDF can be many times what the upload form allows. Most converters stop once the PDF exists, so you go looking for a compressor, guess a setting, and try the upload again.

Here the size is part of the job. pdfly measures the real PDF and only compresses when that number is over your limit. You see the result size before you download, and a PDF over your limit is never handed out.

A JPG is already compressed. Many converters decode it and save it again, which loses a little detail even when the PDF has room to spare. pdfly puts an upright JPG into the PDF byte for byte, so the conversion itself costs nothing. A PNG is stored losslessly.

When the PDF is over your size, the images are recompressed at the highest quality that still fits, and their resolution is lowered only when quality alone is not enough. Rasterizing is the last resort and runs only when you tick the box. Compress a PDF without losing quality explains each pass in more detail.

Every page takes the shape of its image, with no white border, so a landscape photo makes a landscape page and a tall receipt makes a tall one. The long edge of each page is 11.7 inches, the long edge of A4, so the pages print at a sensible size and the image keeps a real resolution in dots per inch.

Phones often save a photo sideways and only record which way up it was taken. pdfly reads that note and turns the page upright, so a portrait photo does not end up lying on its side in the PDF. Such a photo is saved once at high quality after it is turned.

Visa, job, school, and benefit portals often ask for a passport page, an ID card, or a certificate as one PDF under a fixed size. Photograph each page in good light, add the photos in the order the form lists them, and pick the portal's limit. Cropping the photo to the document before you add it saves space that would otherwise go to the table underneath.

If the result cannot fit and the portal accepts several files, convert with a larger size and then split the PDF by size. If some documents are already PDFs, convert the photos first and then merge PDFs under a size limit.

PNG works the same way as JPG, and you can mix the two in one PDF. Screenshots and scans saved as PNG stay sharp because PNG is stored without loss. A transparent PNG, such as a logo or a signature, is laid on a white page, the way it would look printed.

One conversion takes 1 to 20 JPG or PNG images, up to 100 MB together. The size can be anything from 8 KB to 100 MB. HEIC, WebP, and GIF are not accepted. To shrink a PDF you already have, use the PDF compressor. The uploads and the PDF are deleted within 1 hour, and there is no account to create.
