Image to PDF
Convert images to PDF documents
100% Private: All processing happens in your browser. Your files never leave your device.
This tool combines several photos or images into a single PDF, entirely in your browser — nothing is uploaded anywhere. Drop in multiple files (JPG, PNG, WEBP, GIF, BMP, TIFF, HEIC, AVIF and SVG are all accepted, up to 20 MB each), drag them into the order you want, and each one becomes its own page. JPG and PNG files are embedded directly into the PDF; every other format is first re-encoded to PNG on a canvas so it can be embedded, which also happens automatically as a fallback if a file fails to embed directly (an unusual CMYK JPEG, for instance).
Page sizing is your choice: Fit to Image makes each page exactly the size of its photo, so nothing is cropped or padded; A4 and Letter instead place the image on a fixed, standard page and scale it — up or down, whichever the photo needs — to fill the page while keeping its aspect ratio and centred, which can leave white space on one side if the photo's proportions don't match the page. Because scaling up doesn't invent new detail, a small or low-resolution photo enlarged to fill an A4 or Letter page can come out visibly softer than it looked at its original size. If an image can't be converted even after the fallback, it's skipped and you're told how many were dropped rather than the whole batch failing silently. This is a straightforward page-per-image assembly, not a scan-cleanup tool — it doesn't straighten, crop, or deskew a crooked phone photo for you, so hold the camera reasonably level before you shoot the pages you're combining.
How it works
1. Drop your images
Select or drag in as many images as you need, up to 20 MB each. Non-image files are silently skipped with a count of how many were left out.
2. Drag to set page order
Each image is listed with a Page N label. Drag any image by its grip handle to reorder it — the order in the list becomes the page order in the finished PDF.
3. Choose a page size
Pick Fit to Image (the page matches each photo's own dimensions exactly), A4 (595.28 × 841.89 pt), or Letter (612 × 792 pt). With A4 or Letter, every image is scaled to fit the page while keeping its proportions, then centred.
4. Convert and download
Press Convert N Images to PDF. The result downloads as images.pdf — the filename is fixed, so rename it after downloading if you want something more specific.
When you'd use it
Combining several photos of one document into a single PDF
A multi-page form, ID document, or handwritten submission photographed as separate images can be assembled, in the right page order, into one PDF file — exactly what most portals ask for instead of a folder of loose photos.
Submitting phone-scanned pages to an online form
Application portals, exam boards and government sites commonly require a single PDF upload rather than individual image attachments. Photograph each page with your phone, reorder them here, and convert straight to one file.
Building a PDF from a photo set for printing or sharing
A batch of photos meant to be viewed or printed in sequence — receipts for an expense claim, product photos, ID copies for a form — becomes one shareable file instead of several separate attachments.
Standardising mixed-size photos onto uniform pages
When your images come from different cameras or crops with different dimensions, choosing A4 or Letter puts every page at the same fixed size, which some upload portals expect, rather than leaving each page sized to its own photo.
A4/Letter vs Fit to Image
Fit to Image sets each PDF page to the image's own pixel dimensions, so nothing is cropped, stretched or padded — useful when the finished PDF is for your own records and you just want an exact copy of each photo as a page.
A4 and Letter instead place your image on a fixed-size page and scale it — enlarging a small photo just as readily as shrinking a large one — to fit the page while preserving its aspect ratio, then centre it, so a photo that isn't the same shape as the page will have white margins on two sides. Because scaling up doesn't add real detail, a small or low-resolution photo placed on an A4 or Letter page can come out visibly softer than it looked at its original size; Fit to Image avoids that entirely, since it never resizes the photo at all. Choose A4 or Letter when a form or portal specifically asks for a standard page size, and Fit to Image when you'd rather keep every photo at its native resolution.
Several photos into one PDF, in the right order
Every image you drop in becomes exactly one page, in list order — there's no automatic sorting by filename or timestamp, so if your camera roll isn't already in the order you want, drag images by their grip handle to rearrange them before converting. This matters most for multi-page forms and documents, where page order is part of what makes the PDF valid for submission.
Phone photos for form uploads
Because this tool accepts whatever your phone actually saves — including HEIC from iPhones and formats like WEBP and AVIF — you can photograph a document page by page and convert the set directly, without first converting each photo to JPG separately. It re-encodes anything that isn't already JPG or PNG through a canvas step automatically, so the format your phone used doesn't need to match what the portal expects; only the final PDF does.
Frequently asked questions
Can I combine multiple photos into one PDF?
Yes. Every image you add becomes its own page in a single PDF, in the order shown in the list, which you can change by dragging images before converting.
What's the difference between A4/Letter and Fit to Image?
Fit to Image sizes each page exactly to its own photo's dimensions, so nothing is cropped, padded, or resized. A4 (595.28 × 841.89 pt) and Letter (612 × 792 pt) instead place the image, scaled up or down to fit the page and centred, onto a fixed standard page size — a small or low-resolution photo can look softer once enlarged this way, so pick Fit to Image instead if keeping the photo at its original resolution matters more than a standard page size.
How do I control the page order?
Drag any image by its grip handle to move it up or down the list before converting; the order in the list is the page order in the finished PDF.
Which image formats can I upload?
JPG and PNG are embedded directly. WEBP, GIF, BMP, TIFF, HEIC, HEIF, AVIF and SVG are automatically re-encoded to PNG on a canvas so they can be embedded — the same fallback also kicks in if a JPG or PNG fails to embed directly.
Is there a size limit for my photos?
Each image can be up to 20 MB. There's no fixed limit on how many images you combine, though a very large batch will take longer to process since everything runs in your browser tab.
What is the downloaded file called?
The PDF always downloads as images.pdf — the filename doesn't change based on your source photos, so rename it after downloading if you need something more descriptive.
