TL;DR. Combine one or many JPG, PNG, or HEIC images into a single PDF directly in your browser with PDFKits JPG to PDF. Files never leave your device — important when the images are receipts with bank account numbers, scanned ID documents, medical paperwork, or anything that needs to go to an HR portal or government form. Control page size (A4, US Letter, fit-to-image), orientation, and compression quality. Free, no signup, no per-day quota. Alternative tools (Smallpdf at $108/year, Adobe Acrobat at $29.99/month) either upload to the cloud or require a paid plan beyond 2 files per day.
Three things happen when images become PDFs: they merge into a single file, they get a defined page size and orientation, and they become a standard format that nearly every system accepts. A pile of 12 receipt photos becomes one 2 MB PDF that an expense report system will accept. A passport scan, a visa photo, and a bank statement become one upload-ready document for a visa application. A real estate listing's 30 photos become a single PDF a buyer can scroll through offline. The common pattern is consolidation: many images → one shareable, printable, archive-ready document.
The image-to-PDF step also encodes intent. A folder of JPGs is "some photos." A PDF named 2026-Q1-receipts.pdf is an expense report. The format implies finality: PDFs are read, not edited; they are filed, not browsed. Government portals, HR systems, court filings, and most document management systems prefer PDFs explicitly because they preserve a "document" identity that loose images do not.
Mira photographs every receipt with her phone as she works through a client trip — coffee, taxis, dinners, the printing run. At the end of the trip she has 14 JPGs. JPG to PDF combines them into 2026-trip-expenses.pdf with each receipt on its own A4 page, ordered chronologically. The client's expense system accepts a single PDF per trip; submitting 14 separate JPGs is not an option.
James is applying for a Schengen visa. The application requires photos of his passport bio page, his employment letter, his bank statements, and his travel insurance — each as a PDF. He uses JPG to PDF on each scan, sets US Letter page size, and uploads the individual PDFs into the embassy portal. The whole process takes under five minutes.
Carlos lists residential properties and needs to send a packet to each interested buyer: 25 listing photos, the property disclosure form (already a PDF), and the agent contract. Converting the 25 JPGs to a single PDF with image-fit page sizing produces a buyer-ready document he can email without 25 separate attachments.
Aisha takes paper notes in seminars and photographs them at the end of each week. JPG to PDF combines each week's photos into a single archived PDF for the term, sized A4 to match her printed handouts. She names the files by week (week-3-notes.pdf) and stores them in her dissertation folder.
Diego is a residential contractor. Each project produces dozens of progress photos — before, during, and after — that he sends to the homeowner as a project record. Converting daily photos into a single PDF makes the record easier to share, archive, and print if a dispute arises later.
Hannah scans her kids' school forms, medical authorizations, and field-trip permission slips with her phone. JPG to PDF combines them into a single PDF per child per term, kept in a "school records" folder. When the school requests proof of a signed form, she has it as one searchable document rather than 30 phone photos.
Drag your images into JPG to PDF — JPG, PNG, HEIC, and WebP are all accepted. The images appear in a sortable list; drag them up or down to set the order they will appear in the PDF. Choose a page size: A4 (most international use), US Letter (American forms), or Fit to image (each page sized to the image's aspect ratio). Pick orientation if relevant (auto-detection usually picks the right one). Click Convert. The browser does the work — encoding each image, building page structures, embedding metadata. Download the finished PDF, typically within 2–5 seconds even for 30+ images.
If file size matters (an HR portal that caps uploads at 5 MB), use the quality slider before converting, or run Compress PDF on the result. For images shot with a phone at 12 megapixels, the default quality usually produces a 200–500 KB-per-page PDF; reducing quality slightly can halve that without visible degradation on screen.
JPG / JPEG — the universal format. Always works. Best for photographs and scanned documents.
PNG — works perfectly. PNG transparency becomes a white background on the PDF page (PDFs do not have a global transparency channel for pages).
HEIC — Apple's default photo format on iPhones since iOS 11. PDFKits converts HEIC directly; many other tools fail on HEIC and require you to convert to JPG first.
WebP — modern web image format. Supported. Quality is preserved when embedding.
TIFF, BMP, GIF — accepted but usually overkill for source images. Convert to JPG first if you want predictable output.
The most common pitfall: very large source images (40+ megapixels) make a heavy PDF. If a four-image PDF comes out at 15 MB, the source images were huge. Downsize them in your phone's photo app or run Compress PDF on the result.

The privacy axis is the meaningful difference. For images that are not sensitive — vacation photos, public-domain documents — any tool works fine. For images that are sensitive — financial records, ID documents, anything you would not post publicly — browser-only conversion eliminates the question of what happens to the file on the vendor's server.
Photograph documents in good light, not flash. Phone-flash photos of paper documents produce harsh shadows and uneven exposure. A document laid flat under a desk lamp or near a window produces a noticeably better PDF.
Crop before converting. Cropping in your phone's photo app removes the desk surface, your hand, and other clutter — making each PDF page look intentional. The PDF page size also better matches the document if the image is already cropped to it.
Set a consistent order. If you are submitting a packet (visa application, expense report), keep the order consistent across submissions. Reviewers grade on findability — knowing the bank statement is always on page 3 is faster than searching.
For ID documents, redact backgrounds. A phone photo of a passport often shows the room behind it. Crop tight or use the redact tool to remove anything not part of the ID itself, especially if the image will be shared.
For receipts, OCR after. If you need to extract amounts and dates from receipts (e.g., to populate an expense form), convert images to PDF first, then run OCR PDF on the result. The output is a searchable receipts archive.
By default, yes. PDFKits embeds JPG images at their original quality. PNG images are embedded losslessly. Only if you explicitly use a quality slider or run Compress PDF afterward does any quality reduction occur.
No artificial limit. The practical ceiling is browser memory — usually around 200 images on desktop, 50–80 on mobile, depending on the image size.
Yes. PDFKits supports HEIC natively. Open the tool on your iPhone in Safari, choose the photos from your camera roll, and convert. No "Save as JPG" intermediate step needed.
Yes. PDFKits works in Safari (iOS) and Chrome (Android). The interface is touch-friendly. For phones, watch the file count — heavy operations can exhaust mobile browser memory.
PDFKits reads the EXIF orientation tag in your images and rotates accordingly. Sideways phone photos appear right-side-up in the PDF.
Not as part of JPG to PDF, but you can run Page Numbers afterward to add automatic numbering, or annotate before converting.
Print-to-PDF prints whatever is on screen, including window chrome, browser interface, etc. JPG to PDF reads the source image files directly and produces clean, full-quality pages. JPG to PDF is the right choice for combining multiple images.
Not by default — the images are images, not text. To make a PDF made from photographed documents searchable, run OCR PDF on the result. This adds a text layer over the images.
Yes, in two steps. First, use JPG to PDF to convert the images. Second, use Merge PDF to combine the image PDF with the existing PDFs in the desired order.
EXIF metadata from JPG images is partially preserved during embedding. For documents you plan to share publicly, run Clean Metadata on the resulting PDF to strip GPS coordinates, camera serial numbers, and timestamps.
