Image to PDF Converter: Complete Feature Guide
This free online tool turns photos and pictures into a PDF file. No signup, no upload to a server—everything runs in your browser. Below is a simple, detailed explanation of every feature so you know exactly what you can do before you click Convert.
1. Upload images (drag & drop or click)
You can add pictures in two ways: drag files onto the dashed upload area, or click that area to open your computer’s or phone’s file picker. You can select several files at once. A short loading state shows while images are being read. After the first batch is in, the drop zone hides and you work from the selected-images list instead.
2. Supported formats: PNG, JPG, JPEG, GIF, and WebP
The converter accepts everyday photo types: PNG, JPG/JPEG, GIF, and WebP. You can mix them in the same PDF—for example a phone JPEG, a screenshot PNG, and a WebP from the web. Files that are not images are ignored, so a random PDF or Word file dropped by mistake will not be added. If nothing valid is selected, you get a clear message to pick a supported image.
3. Animated GIFs keep every frame
A PDF file cannot play a looping cartoon the way a browser does—viewers like Chrome show still pages. If you drop an animated GIF, the preview still plays the motion in the card. When you convert, the default is All frames on one page: every frame is laid out in a grid on a single PDF page, in order, so you can see the whole animation at once. A 10-frame GIF becomes one page with 10 pictures. You can instead choose All frames (one page each) for a flipbook, or First frame only for a still poster. This setting appears when a GIF is in the list.
4. Many images become one PDF (one image per page)
Each picture becomes its own page, in the order you set. Two photos make a two-page PDF; twenty photos make twenty pages. This is useful for scanned homework, receipt photos, WhatsApp screenshots, or a set of slides you want to email as a single document instead of a folder of files.
5. Selected-images preview with name, size, and resolution
After upload you see a grid of cards. Each card shows a thumbnail, the file name, the file size (for example 1.97 MB), and the pixel size (for example 1536 × 1024). An orange number on the card is the page order in the PDF. Thumbnails are smaller copies made for a fast screen; the original image is still kept for the real PDF so quality is not thrown away just to show a preview.
6. Add more images later
Forgot a photo? Click “Add More Images” and pick extra files. New cards slide in at the end of the list without wiping what you already chose. You can keep adding batches until the set is complete, then convert once.
7. Remove one image or clear everything
Hover (or tap) a card and use the trash icon to drop that one picture. The remaining numbers update so page 2 becomes page 1, and so on. “Clear All” asks you to confirm, then removes every image and brings back the empty upload area so you can start over.
8. Drag cards to change page order
The PDF follows the grid, not the order files were picked from your folder. Press and drag a card to a new place. The orange numbers refresh right away. When you convert, the tool reads that on-screen order, so the first card is page 1 and the last card is the last page.
9. Page size: A4, Letter, Legal, A3, and A5
You choose the paper size of the finished PDF. A4 (210 × 297 mm) is the usual size in most countries. Letter (8.5 × 11 in) is common in the US. Legal is taller than Letter. A3 is a large sheet, useful for posters or wide drawings. A5 is a small booklet size. Pick the size you will print or the size a school or office asked for.
10. Portrait or landscape pages
Portrait is taller than it is wide (like a printed letter). Landscape is wider than it is tall (like a photo from a phone held sideways, or a spreadsheet screenshot). Every page in the file uses the same orientation you pick here, so a whole album stays consistent.
11. Image fit: Fit to Page, Fill Page, or Actual Size
This setting controls how each picture sits on the paper. Fit to Page (the default) shrinks or grows the image so the whole picture is visible inside the margins. Nothing is cut off; you may see white space around a photo that does not match the page shape. Fill Page scales the image until the page is fully covered. The picture keeps its shape, so leftover edges can be cropped. Use this when you want a photo to look like a full-page print. Actual Size tries to place the image at its real pixel size (about 96 pixels per inch). If it is too big for the page, it is scaled down to fit, same idea as Fit to Page. Small icons stay small and sit in the center instead of being stretched wall to wall.
12. Margins you can set (0 to 50 mm)
Margin is the empty border around the image. The default is 10 mm. Set it to 0 if you want the picture as close to the paper edge as possible. Raise it (up to 50 mm) if you need space for hole punches, notes in the margin, or a cleaner look when printing. The image is always centered in the remaining space.
13. Transparent PNG, GIF, and WebP stay clean (no black box)
Logos and stickers often have a see-through background. In the selected-images grid, those pictures show on a light checkerboard so you can tell which parts are empty. When the PDF is built, empty pixels are placed on white—the same color as a normal PDF page—so you do not get a black rectangle behind a logo. Ordinary JPEG photos are unchanged. This matters for company marks, app icons, and screenshots with rounded corners.
14. Phone photos keep the right rotation
Many camera JPEGs store “this photo was taken sideways” in hidden EXIF data instead of rotating the pixels. The converter draws each image through your browser first, so that orientation is applied. A portrait from your phone should land upright in the PDF instead of on its side.
15. Convert with a live progress bar
Click Convert to PDF when the order and settings look right. A progress bar walks through each picture (for example “Processing image 3 of 12”). If one file fails, that page is skipped and the rest still finish—you are not stuck with an empty download because of a single broken image. When it is done, the browser saves a file named like converted-images- plus a timestamp, for example converted-images-1730000000000.pdf.
16. Built for phones and slower devices
On a phone, the layout stacks so buttons and settings are easy to tap. The tool also notices a low-power device and uses slightly smaller preview thumbnails and gentler processing chunks, so a long batch is less likely to freeze the tab. You can still convert on desktop, tablet, or mobile with the same features.
17. Everything runs in your browser (privacy and no signup)
Reading the images, building the pages, and creating the PDF all happen on your device. The pictures are not sent to our servers. You do not create an account or log in. That makes the tool safe for ID photos, invoices, medical slips, and school work you would not want sitting on someone else’s computer. After the page has loaded, the conversion itself is local.
18. Free to use, as many times as you need
There is no paywall, no daily cap in the tool, and no watermark stamped on the PDF. Open the page, add images, download. Repeat for the next set. For very large batches, converting in groups of about 20–30 images is kinder to your computer’s memory, but there is no hard “maximum files” lock in the converter itself.
19. Everyday uses: scans, homework, receipts, and photo albums
Students turn notebook photos into one file to submit. Offices pack signed forms or bills into a PDF for email. Shops combine product shots for a catalog page-set. Families put vacation pictures in order and share a single document. If you already have a PDF and need the opposite direction, use our PDF to Image tool; if you need to join existing PDFs, use Merge PDF. This page is only for pictures going into a new PDF.
In short: drop your images, drag them into the right order, pick paper size and how the photo should sit on the page, then download one PDF—all online, for free, without sending files to a server. If you have more questions, check the FAQ below.
