How to Convert Images to PDF
Most image-to-PDF tools force you to pick a format first: JPG here, PNG there, and no help at all if half your files came off an iPhone as HEIC. This one takes whatever you have. Drop JPGs, PNGs, WebPs, HEICs, GIFs and AVIFs together and they all become pages of a single ordered PDF — converted inside your browser, so passports, certificates and bank documents never touch anyone else's server.
Upload any images
Mix formats freely - JPG, PNG, WebP, HEIC from your iPhone, GIF, AVIF. Each image becomes one page.
Arrange and configure
Reorder pages with the arrows, remove any you do not want, then choose A4, Letter or fit-to-image and set the margin.
Download your PDF
Get a single document with all your images as pages, ready to email, upload or print.
Why a PDF Beats Sending Loose Images
Almost every portal, employer and government office that accepts documents wants one PDF, not a folder of photos. There is a good reason: images have no fixed order, no page structure, and no guarantee of how they will display. Attach eight photos to an email and the recipient sees them sorted alphabetically by filename, which is almost never the order you intended.
A PDF fixes the sequence permanently, renders identically on every device, and prints at the correct physical size. Choosing A4 or Letter here centres each image on a standard page, which is exactly what a printer or a document-processing system expects — while fit-to-image keeps the page the same shape as the photo, ideal for portfolios and screenshots.
This tool also handles the format problem that trips people up constantly: iPhone photos save as HEIC, which many upload portals reject outright. Dropping HEIC files here converts them transparently as part of building the PDF, so you never have to run a separate conversion step first. If you need them as standalone images instead, use our HEIC to JPG converter.
Common Situations This Tool Solves
Submitting documents to a portal
Visa applications, job portals, university systems and government forms almost always demand a single PDF. Photograph your documents, drop them here in order, and upload one clean file.
Photos from an iPhone that portals reject
HEIC files are refused by a huge number of upload systems. This tool decodes them automatically while building your PDF, so there is no separate conversion step.
Turning phone scans into a proper document
A stack of photographed pages is not a document. Ordering them into a PDF with A4 sizing produces something that looks and prints like a real scanned file.
Sharing a portfolio or set of designs
Sending twenty images means twenty attachments in an unpredictable order. One PDF with fit-to-image pages presents your work exactly as you intended it to be seen.
Frequently Asked Questions
Which image formats can I convert to PDF?
JPG, PNG, WebP, HEIC, HEIF, GIF and AVIF - and you can mix them freely in the same document. Each image becomes one page of the final PDF.
Can I convert iPhone HEIC photos directly to PDF?
Yes. HEIC files are decoded automatically as part of building the PDF, so you do not need to convert them separately first. This is exactly what upload portals that reject HEIC require.
How do I combine multiple images into one PDF?
Drop all your images at once - each becomes a page. Use the arrows to reorder them, choose your page size, and click Convert to PDF for a single combined document.
Can I reorder the pages before creating the PDF?
Yes. Every thumbnail has left and right arrows to move it earlier or later, plus a delete button, so you can arrange everything exactly as needed.
Should I choose A4 or fit-to-image?
Choose A4 or Letter for anything printed or submitted to a portal - each image is centered on a standard page. Choose fit-to-image for portfolios and screenshots where you want no white borders.
Does converting images to PDF reduce quality?
JPG and PNG images are embedded without re-compression, so quality is preserved. Other formats are converted at very high quality first, so any loss is visually negligible.
Is it safe to convert private documents here?
Yes. Everything runs inside your browser - your images are never uploaded to any server, never stored, and never seen by anyone. That matters for passports and bank statements.
Is there a limit on how many images I can add?
No hard limit. Because processing happens on your device, very large batches depend on your available memory rather than a server quota.
How do I convert images to PDF on iPhone or Android?
Open this page in Safari or Chrome, tap the upload area, select photos from your gallery, arrange them, and download the PDF straight to your Files app.
Why is my PDF larger than the images I added?
PDF adds a small structural overhead per page. Because images are embedded without re-compression where possible, the size stays close to the sum of your originals. Compress the PDF afterwards if needed.
Can I add page numbers or a watermark to the PDF?
Yes, as a second step. Create the PDF here, then run it through our Add Page Numbers or Watermark PDF tools.
Is this image to PDF converter really free?
Completely free, with no page limits, no watermarks, no signup and no premium wall. Everything runs in your browser, so there are no server costs to pass on.
