Image to PDF converter

Any images in, one PDF out — pages in your order, A4/Letter or exact image size, built in your browser so nothing is uploaded.

JPG, PNG, WebP, AVIF, HEIC, GIF, BMP · each image becomes one page, in this order

No size limit · files are processed on your device and never uploaded · how it works

Advanced settings (optional)
Page options
Page size

Each page is exactly the size of its image — no borders, no scaling.

Conversion quality
100

JPG and PNG files go into the PDF untouched — no quality loss. This slider only applies when other formats (WebP, HEIC…) must be converted.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Image to PDF

  1. Drop your images — JPG, PNG, WebP, HEIC and more; each one becomes a page.
  2. Reorder with the ↑↓ buttons and pick a page size: exact image size, or A4/Letter with margins.
  3. Click Create PDF and download the finished document.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Why quality matters in image-to-PDF converters

Most converters quietly re-encode every image, so photos come out softer than they went in and pictures of documents get JPEG artefacts around the text. This tool embeds JPG and PNG files into the PDF byte-for-byte — the page shows exactly the pixels of your original file, no recompression. Formats PDFs cannot hold natively (WebP, HEIC, AVIF, GIF, BMP) are converted once to high-quality JPEG, with the quality under your control.

Common uses

  • Photos of documents → one file. Phone photos of a contract or ID pages become one orderly PDF for an application form or email. Use A4 with a margin so it reads like a scan.
  • Receipts and invoices for accounting. A month of receipt photos in one dated PDF.
  • Artwork or portfolio pages. “Fit to each image” keeps every page exactly the artwork's size — no borders, no scaling.
  • iPhone photos for forms that want PDF. HEIC photos are decoded right here — no separate conversion step needed.

Getting the file size right

Because JPGs pass through untouched, the PDF is roughly the sum of its images. If the result is too large for an upload limit, compress the images first with the image compressor (or use the resizer's exact-KB target), then rebuild the PDF — you choose the trade-off instead of a converter choosing it for you. The file-size guide explains what to aim for.

Frequently asked questions

Does converting images to PDF lose quality?

Not here for JPG and PNG: the original file bytes are embedded into the PDF untouched, with zero recompression — the PDF page contains exactly the pixels of your file. Other formats (WebP, HEIC, AVIF) are converted to high-quality JPEG first, with a quality slider under Page options.

How do I put multiple photos into one PDF?

Drop them all at once (or add more later) — each image becomes one page, in the order of the list. Use the ↑ and ↓ buttons to reorder before creating the PDF.

Which page size should I pick?

“Fit to each image” makes each page exactly the image’s size — best for digital sharing and pictures of documents. A4 or US Letter centres each image on a standard page with a margin — best when the PDF will be printed or must look like a scanned document.

Are my photos uploaded to a server?

No. The PDF is assembled entirely in your browser using the open-source pdf-lib library. You can load the page, disconnect from the internet, and still create PDFs — nothing is transmitted anywhere.

Is there a limit on the number of images?

No fixed limit — hundreds of images work. The practical limit is your device’s memory: very large batches of huge photos may need to be split into two PDFs.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
