What Is an Image to PDF Converter?
An image to PDF converter takes one or more image files (JPG, PNG, WebP, HEIC) and packages them into a single multi-page PDF. Each image becomes one page, with control over layout (fit-to-page, original size, custom margins), page size (A4, US Letter), and orientation (portrait, landscape). PDFs handle multi-image workflows far better than zipping a folder of images: recipients get one file that prints in order, scrolls naturally, and can be password- protected.
The audience includes anyone digitising paper documents (receipts, signed contracts, ID cards, passport scans), photographers building proof sheets, students compiling photo essays, real- estate agents handing buyers a portfolio of property shots, and travelers consolidating boarding passes and reservations into one file. The Tooldit converter runs entirely in your browser, so even sensitive scans like passports or financial receipts stay on your device.
Combine Images into One PDF, Free and Private
Have a stack of photos, receipts, or scanned pages that need to travel together? Converting image to PDF wraps them into one tidy, universal file that opens on any device and is easy to email, print, or upload. Tooldit builds the document entirely in your browser, so your pictures — including IDs and personal paperwork — are never uploaded to a server.
Control How Your PDF Is Laid Out
This is more than a plain merge — you decide how each page looks before you export:
- Page size — pick A4, US Letter, or Legal, or choose Fit Image to size each page exactly to the photo.
- Orientation — portrait, landscape, or auto, which rotates the page to match each image.
- Margins— add breathing room from none up to large, so images aren't crammed to the edge.
- Order — rearrange images with the up and down arrows so pages land in the right sequence.
Why Use Tooldit's Image to PDF Converter
- 100% private — the PDF is built locally with an in-browser engine; nothing is uploaded.
- Free, no watermark — unlimited conversions with no account and no stamp on your pages.
- JPG, PNG, and WebP — mix formats freely; WebP is handled automatically.
- Full-quality images — JPG and PNG are embedded as-is, with no re-compression.
- One clean file — many photos become a single, easy-to-share PDF.
When You'd Turn Images into a PDF
- Applications and forms — combine scanned pages or photos of a document into one PDF a portal will accept.
- Receipts and expenses — bundle snapshots of receipts into a single file for an expense report.
- Portfolios and lookbooks — turn a set of images into a clean, ordered document to send a client.
- One attachment, not ten — email a single PDF instead of a dozen separate photos.
- Combining receipts for expense reports — finance departments often require a single PDF of receipts per trip or per project. Drop the photos in chronological order and export one tidy expense bundle.
- Photo albums in PDF format — sharing event photos with extended family who don't use cloud galleries. A PDF album is universally openable and doesn't require a Dropbox or Google account.
- Submitting ID documents to government portals — passport, driver's licence, and proof-of-address photos often need to be submitted as a single PDF for visa applications, tax filings, and KYC checks.
- Product portfolios for e-commerce — sellers compiling product photos into a PDF catalogue to share with wholesalers or pitch decks.
- Archiving WhatsApp/chat screenshots — keeping a permanent record of important conversations, especially for legal disputes or personal archives. PDFs are easier to search and store long-term than individual image files.
Already have a PDF and need the pages as pictures instead? The PDF to Images tool does the opposite, and Merge PDF joins finished PDFs together.
Image to PDF vs Other Tools
Versus iOS Print > Save as PDF — iOS lets you save any photo as PDF via the share-sheet's print preview, but only one image at a time. Tooldit handles multi-image batches in one go.
Versus Adobe Scan / Microsoft Lens — scan apps capture images and convert them directly to PDF with built-in edge detection and perspective correction. They're excellent for document scanning but require app install. Tooldit handles already-captured images.
Versus online converters — most online image-to-PDF services upload your images. For sensitive scans (passports, IDs, signed contracts), this is a privacy risk. Tooldit runs in your browser.
Versus Preview "Save as PDF" on Mac — macOS Preview can combine images into a PDF via File > Print > Save as PDF, but it's Mac-only and the UI is fiddly. Tooldit works cross-platform.
Troubleshooting & Common Issues
- Images appear in wrong order — PDF page order follows the order images are added. Use drag-to-reorder before converting, or pre-sort filenames (e.g. 01.jpg, 02.jpg) and add in batch.
- Output file is huge — PDFs embed images at full resolution by default. For smaller files, downscale source images first or use the "compress images" option to embed JPGs at reduced quality.
- Image looks pixelated in the PDF — the source image is below the rendered size. PDFs can't synthesize detail that wasn't there. Use higher-resolution sources or smaller pages.
- HEIC photos won't upload — some browsers can't decode HEIC natively. Convert HEIC to JPG first with the HEIC converter.
- Mixed portrait and landscape images — each page can keep its source image's orientation, or all pages can be forced to one orientation. Pick the right option based on your output goal.
- Transparent PNGs get black background — PDFs don't render image transparency the same way. Flatten transparent PNGs onto a white background first if you want a clean white page.
Frequently Asked Questions
+Can I combine several images into one PDF?
Yes. Add as many JPG, PNG, or WebP images as you like, use the arrows to set their order, and they are merged into a single PDF in that exact sequence.
+Which image formats can I use?
JPG, PNG, and WebP are all supported. JPG and PNG are embedded directly, and WebP is converted to PNG first so it stays sharp and lossless.
+Can I pick A4 or US Letter page size?
Yes. Choose A4, US Letter, or Legal, or use Fit Image to size each page to the photo. You can also set portrait or landscape orientation and a page margin.
+Are my images uploaded anywhere?
No. The PDF is assembled in your browser, so your photos and documents never leave your device and nothing is stored on a server.
+Will converting to PDF reduce image quality?
No. JPG and PNG images are embedded at their original quality with no re-compression, so the pictures in your PDF look exactly like the originals.
+How many images can I combine?
There's no fixed cap, but practically the browser handles 50–200 images comfortably depending on resolution. For very large image batches, split into smaller conversions and merge the resulting PDFs.
+Can I reorder images before converting?
Yes. Drag the thumbnail strip to reorder, or use the up/down arrows. The PDF's page order matches the final order you see.
+Are my images uploaded anywhere?
No. The PDF is built entirely in your browser using pdf-lib. Images are read locally, embedded into the PDF, and the result downloads to your device. Nothing is uploaded.
+Can I add multiple images per page?
This tool puts one image per page by default so each photo gets the full page area. For collage-style multi-image pages, use the image merge tool to combine images into one image first, then convert that merged image to PDF.
+How do I control image quality in the output PDF?
JPGs are embedded at their original quality (no re-encoding), so output quality matches the source. To shrink the final PDF, downscale or re-save the source images at lower quality before adding them, or run the resulting PDF through compress PDF for size-vs-quality trade-offs.
