How to

How to convert JPG to PDF under 1 MB

  1. 1.

    Add your pages. Photos or scans of each page, or a PDF you already have, in the order they should appear. About 10 to 15 scanned A4 pages stay readable under 1 MB.

  2. 2.

    Keep the 1 MB limit. It is already set. The tool builds the PDF, or compresses yours, until it is under 1 MB: about 500 KB a page for two pages, 200 KB for five.

  3. 3.

    Download the PDF. Check the size shown, then upload it to your form.

Why this size

Why forms ask for a PDF under 1 MB

1 MB means 1,000 KB or 1,024 KB, depending on who counts. The PDF made here stays under 1,000,000 bytes, so it passes either way. That is room for 10 to 15 scanned pages, or several photos at full quality.

A single phone photo is often 2 to 5 MB on its own, so even one photo may need compressing to fit. The tool works as a JPG to PDF compressor: it builds the PDF, then lowers quality only until the file is less than 1 MB. To see what a size in MB means in KB, use the MB to KB converter.

Tips

Tips that make a difference

Keep color where it matters

Stamps, seals and photo IDs read better in color, and at this size there is room for it.

One PDF for a whole file

Statements, letters and bookings can go into one PDF here: add them all, then download one file.

Fewer pages, sharper text

1 MB is shared by all pages. If a form allows separate uploads, one document per PDF looks better.

FAQ

JPG to PDF under 1 MB: questions

How do I make a photo PDF less than 1 MB?
Add the photo or photos, keep the 1 MB limit and download. The PDF is compressed on your device until it is less than 1 MB.
Is 1 MB 1000 KB or 1024 KB?
Both are in use. Upload forms count 1 MB as 1,000 KB or 1,024 KB; the PDF made here stays under 1,000 KB, so it fits both.
Can I compress a JPG to 1 MB without making a PDF?
Yes. Use the image compressor, switch the size to MB and type 1; the photo stays a JPG.
How do I convert JPG to PDF under 1 MB?
Add your photos, keep the 1 MB limit and download. The PDF is built and compressed on your device until it fits.
How many pages fit in 1 MB?
About 10 to 15 A4 pages of scanned text stay comfortably readable. Photos with lots of detail need more space per page.
How do I compress a PDF to 1 MB?
Add the PDF here instead of photos and keep the 1 MB limit: the tool reduces the PDF size until it is under 1 MB. The photos inside are compressed first, so typed text stays text; only if that is not enough are the pages saved as images.
What if the PDF cannot get under 1 MB?
You will see the size it reached. Crop the photos to the page, add fewer pages, or use a larger limit if your form allows it.
Are my documents uploaded?
No. The PDF under 1 MB is built in your browser, so certificates, IDs and other private documents never leave your device.

Checked

How we checked this page

Checked by the SizePort team on .

We test the tool with sample photos before it goes live and check that the sizes on this page match what it produces. Rules and platforms change, so if something here is out of date, tell us and we will correct it.

How the tool works

Each image becomes one page of a PDF built in your browser, and a PDF you add keeps all its pages, in the order you add the files. With a size limit, the tool first compresses the photos inside the PDF, quality first and size second, while typed text, links and drawings stay as they are, so the text can still be selected. Only if that is not enough is each page drawn with pdf.js (Mozilla, Apache 2.0) and saved as an image, smaller pages before lower quality, until the whole file is under the limit. Nothing is uploaded. Everything happens in your browser; your images are never uploaded.
