JPG to PDF 500 KB

500 KB is 512,000 bytes, a roomy budget for photos in a PDF. It holds 6 phone photos of pages at the default setting, with the pictures at 150 dpi, and 25 at the smallest. Build the PDF first, then compress it to the target.

What 500 KB holds

A phone photo of a page comes down from about 2.7 MB to about 73 KB at the default setting, and to about 18 KB at the smallest. So 500 KB holds 6 photos with the print sharp, or 25 at the smallest setting. To make a PDF of less than 500 KB from JPG files, this free converter does both steps in the tab.

The 500 KB page shows what fits for every kind of document.

The downsample step

When the images have more pixels than the page can show, the compress step reduces them. A phone photo is often four thousand pixels wide, while an A4 page at 150 dpi needs about 1,240. Those extra pixels cost bytes and show nothing.

So the first thing to go is resolution nobody could see, not detail anyone was using. The compress tool reports the size it reached and the method that won.

Running the two steps

Start at the images to PDF tool, drop the photos in, set the page size and margin, and get a PDF that keeps the original pixels. Then take it to a 400 KB target or straight to 500 KB, depending on how strict the form is.

Both steps run inside the tab. The photos are read from disk, worked on in memory, and written back to your downloads folder. Nothing is uploaded and nothing is kept.

Questions people ask

How many photos fit in a 500 KB PDF?
6 at the default setting, where printed text stays sharp, and 25 at the smallest setting.
Does the tool reduce my photo resolution?
It can, when the photo has more pixels than the page needs. A four thousand pixel wide phone photo on an A4 page carries detail no viewer will show, and that is the cheapest thing to remove.
Is 500 KB enough for photos of an ID document?
Yes. The two sides of one card fit at the default setting with room to spare, so the small print and the photo on the card stay readable.
Can I set the page size when converting JPG to PDF?
Yes. The images to PDF step lets you choose the page size and the margin, so the photos sit on a real page. That choice also decides how many pixels each page needs.
