JPG to PDF Under 1 MB
A 1 MB cap is roomy for one page but tight for a stack of scanned pages, such as a transcript, a set of receipts or a signed contract. Upload all the photos and they come out as one PDF that stays under 1 MB.

White space around each image: small is 5 mm, medium 10 mm, large 20 mm. Ignored when page size is the same as the image.
Fit shows the whole image with white space if the shapes differ; fill covers the page and crops the edges; actual size places it at its print size from DPI.
Put 2 or 4 images on each page in a grid, for ID cards front and back or contact sheets.

JPEG quality of photos inside the PDF. 85 keeps them sharp; with a target size this is the starting point.
How to use this tool
- 1
Upload every page
Add the JPGs in one go, up to 50. Page order is set to File name, so photos named page1, page2 and so on fall into place; drag thumbnails to change it.
- 2
Keep the 1 MB target
PDF file size is on Target size with Max size 1 MB and Letter pages. Choose A4 for portals outside North America.

Convert and check
Press Convert to PDF, scroll through the result and read the smallest line on the busiest page before you submit.
How a 1 MB budget is shared between pages
In a PDF built from photos, almost every byte belongs to the images; the structure that ties pages together adds a few kilobytes per page. So a 1 MB file is roughly 1,000 KB divided between your pages. Ten pages get about 100 KB each, which at 150 DPI on Letter, 1275 × 1650 pixels, still reads cleanly if the paper was photographed in good light.
When the target is tight, the converter first lowers JPEG quality from the starting point of 85, then lowers resolution. For text, slight softness reads better than smudgy edges, so crop photos tightly to the paper before a many-page conversion.

JPEG image
JPEG (or JPG) is the most widely used photo format, standardised by the Joint Photographic Experts Group in 1992. It uses lossy compression that discards fine detail the eye is unlikely to notice, which keeps photos small enough for the web, email and phone storage. It handles smooth gradients and natural scenes well, but sharp text, line art and flat colours pick up visible blocky or fuzzy artefacts. JPEG has no transparency and no animation, and every re-save loses a little more quality. Every browser, phone, camera and image editor can open it.

Portable Document Format
PDF was created by Adobe in 1993 and became the open ISO 32000 standard in 2008. It fixes text, fonts, images and layout so a document looks the same on every screen and printer. PDFs can contain forms, signatures, links, attachments and searchable text, and the PDF/A variant is used for long-term archiving. The fixed layout makes PDFs hard to edit, and scanned PDFs contain only images unless OCR is applied. Every browser and operating system can open them.

Several JPGs are merged into a PDF under 1 MB because job, university and court systems want each document as one file of limited size, and loose photos of separate pages are either rejected or lost in review.
JPG to PDF 1 MB for jobs, universities and courts
Applicant tracking systems let each employer set its own attachment limit, and caps between 1 MB and 5 MB per file are often seen. A certificate set or a portfolio of scanned pages at 1 MB passes nearly all of them.
- Upload a text resume separately if the form parses it
- Name the file after yourself and the document
Admissions and transcript portals often limit each upload, and some want every transcript page in one PDF; under 1 MB is a safe size.
- Keep pages in order: page 1 first
- Include both sides when the back has a grading key
In the US federal CM/ECF system each court sets its own maximum file size, and state systems differ again. Exhibits made from photos are welcome as PDF, but large ones may have to be split into parts.
- Check the clerk's page for size and PDF/A rules
- Split exhibits into several PDFs instead of shrinking them past legibility
When 1 MB is about email, not a form
Personal email services allow far more than 1 MB, but some company and school mail servers cap incoming messages lower, and recipients on slow mobile data appreciate a small file. For a whole photo album where file size is less important than layout, photo to PDF arranges pictures several to a page.
JPG to PDF 1 MB questions
How many pages can a JPG to PDF 1 MB file hold?
Roughly ten typed pages at 150 DPI, or four to six color pages, is a typical result. Photos with lots of texture take more space than clean paper, so the real number depends on what you photographed.
Why do application portals cap uploads at 1 MB when email allows 25 MB?
A portal stores thousands of applications and has reviewers open them in a browser, so small files keep storage and loading under control. Gmail allows 25 MB per message because attachments are one-off. The two limits answer different problems.
Does a court accept a PDF made from photos?
Courts generally accept scanned exhibits as PDF, but rules differ on page size, file size, text searchability and sometimes PDF/A. Read the e-filing rules of your court; if PDF/A is required, tick PDF/A (archive) before converting.
My 1 MB PDF looks worse than separate photos. Why?
Each page gets a share of the 1 MB, so ten pages leave about 100 KB each. Reduce the number of pages, crop margins away, or split the upload if the form allows several files. If a single page has to be sharp, give it its own PDF.
The PDF is already made but is 3 MB. What should I do?
Use compress PDF to 1 MB on the existing file. It recompresses the images inside the PDF to the same target without starting from the photos.
Is 1 MB counted as 1,000 KB or 1,024 KB?
It depends on the site. Windows reports sizes in units of 1,024 bytes, macOS in units of 1,000. If a form is strict, switch the unit to KB and set Max size to 950.
