The image to PDF converter turns a still image into a one-page PDF document. Upload a JPG, PNG, WEBP, HEIC, or any other supported image format, pick a page size (A4, Letter, Legal, Square, or Auto), set margins and orientation, and download a PDF ready to email, print, or attach to a workflow. Up to 50 files per batch, 40 MB per file. Each source image becomes its own single-page PDF.
What the Converter Does
The image is decoded into a memory buffer, the chosen page size is computed in PDF point units (1 point = 1/72 inch, so A4 = 595x842 points renders at exactly 210x297 mm in a viewer), and the image is fitted inside the page with the chosen margins. The image preserves its aspect ratio: if the aspect ratio of the image does not match the page, the alignment setting (start, center, or end) decides which edge the image sits against. The remaining space on the page is filled white. The result is saved as a standard PDF at 72 DPI, the native PDF point resolution.
Page Size Options
- Auto: the PDF takes the image's pixel dimensions directly. No fitting, no white space, no margins applied. The right choice when the goal is a PDF wrapper around the image rather than a printable page.
- A4 (595x842 pt, 210x297 mm): the international standard. Used everywhere outside North America for office and print work.
- Letter (612x792 pt, 8.5x11 in): the North American standard. Used for US and Canadian office and print work.
- Legal (612x1008 pt, 8.5x14 in): the longer US format used for contracts, legal documents, and some forms.
- Square: the page is a square sized to fit the longer dimension of the image. Useful for Instagram-style square layouts intended to print well.
Orientation and Alignment
For A4, Letter, and Legal, the orientation can be portrait (taller than wide), landscape (wider than tall), or auto. Auto picks whichever orientation matches the image's aspect ratio so the image fills the page better. Pick the explicit orientation when the layout matters more than the image content (a portfolio is always portrait, a panorama is always landscape).
The alignment setting controls where the image sits inside the page when there is leftover space:
- Center (default): image is centered both horizontally and vertically. The most common choice.
- Start: image is anchored to the left edge in landscape pages, top edge in portrait pages. Useful for document-style layouts where the image acts as a header.
- End: image is anchored to the right edge in landscape pages, bottom edge in portrait pages. Useful for footer-style placements.
One Image, One PDF
Each source image produces its own single-page PDF. A batch of 50 images produces 50 separate PDFs, returned as a ZIP archive. This tool does not assemble multiple images into a single multi-page PDF document. If your goal is a multi-page PDF containing a sequence of images, you need a dedicated assembler (free desktop tools like pdftk or the print-to-PDF feature in your operating system handle this), or you can submit each image individually here and merge the resulting PDFs afterward.
When Image-to-PDF Is the Right Tool
- Submitting documents to portals that require PDF: tax forms, school applications, insurance claims, and government forms often accept only PDF. Converting a phone photo of a signed form to a properly-sized A4 or Letter PDF makes it accepted.
- Sharing a photo as a printable document: a recipient who will print the image to physical paper needs a PDF sized to their paper format (A4 in Europe, Letter in the US). Auto-sized image dimensions can produce wrong-scale prints.
- Email attachments where the format matters: some workflows specifically expect PDF instead of JPG/PNG. Converting the image first means the recipient does not have to.
- Archival and long-term storage: PDF is one of the most universally supported and longest-lived document formats. A PDF created today will open in viewers 20 years from now without trouble.
- Print shops: most print shops prefer PDF at exact page dimensions because the size in the PDF matches the size on paper. An auto-sized PDF skips this guarantee; explicit A4 or Letter gives them exactly what they need.
Pairing With Other Tools
The image-to-PDF converter often sits at the end of a workflow. Before the PDF step, the image resizer can bring the image to a known dimension that fits the page well, the image cropper can trim the composition, and the image rotator can straighten a scan or fix orientation. For other format conversions (PNG to JPG, HEIC to JPG, etc.) before PDF wrapping, use the main image converter.
Batch Conversion and Privacy
Each conversion runs in memory on the server. Files stream to the converter endpoint, decode into a buffer, get composited onto the chosen page, and return the PDF as base64 inside the JSON response. Nothing is written to disk, indexed, logged, or cached. The buffer is released as soon as the response is sent. Up to 50 files per batch, 40 MB per file. ZIP archives are unpacked server-side and each entry counts against the same 50-file limit. The same page size, orientation, margin, and alignment settings apply to every file in a batch, which is exactly what you want when converting a folder of photos to A4 PDFs for a print run. Outputs are returned individually or repackaged into a single download ZIP.
FAQ
This converter produces one single-page PDF per source image; a batch of 50 images produces 50 separate PDFs. To assemble a multi-page document from a sequence of images, convert each image individually here, then merge the resulting PDFs using a dedicated assembler. Free options include pdftk, the print-to-PDF feature in your operating system, or any free online PDF merger that accepts multiple PDFs and outputs one.
A4 (210x297 mm) is the international standard for offices, schools, and print shops outside North America. Letter (8.5x11 inches) is the North American equivalent and the right choice for US and Canadian printing or submission to North American institutions. Legal (8.5x14 inches) is for contracts and long-form legal documents. Square is for Instagram-style content intended to print well. Auto skips the page-fitting step entirely and produces a PDF at the image's exact pixel dimensions, useful for digital-only sharing where physical size does not matter.
The image is embedded in the PDF using the same encoding it had as a source JPG or PNG, so there is no extra round of compression beyond what the source already had. A high-quality JPG goes into the PDF at the same quality. The only place quality can change is if the page size is much smaller than the image: the image is fitted to the page area inside the margins, which may downscale it. For a high-resolution scan that needs to print at full quality, set margins to 0 and pick a page size that matches the image proportions, or use Auto.
The margin (in PDF points, 0 to 400) sets the white border between the page edge and the image. The default 32 points equals roughly 11 mm, which works for most office printing. For print shops that handle bleed, set the margin to 0 to let the image extend to the page edge. For documents that need a wide white border around a photograph (school assignments, portfolio submissions), bump the margin to 60 to 100 points.
The image is scaled down to fit inside the page area minus margins, preserving its aspect ratio. The unused space on the page is filled white. The alignment setting controls which edge the image sits against: center (default) puts the image in the middle, start anchors it to the left or top edge depending on page orientation, end anchors it to the right or bottom edge. The image is never stretched or distorted to match the page ratio.
Yes. HEIC and HEIF are accepted as input and decoded into the PDF directly, no intermediate conversion to JPG required. This is useful when a portal asks for a PDF of a document photo and you only have the iPhone HEIC original. The resulting PDF opens in any standard PDF viewer regardless of HEIC support on the recipient's system.
Yes, when you pick A4, Letter, or Legal. The PDF is saved at 72 points per inch (the standard PDF resolution), so A4 = 595x842 points = 210x297 mm exactly when opened in any viewer or printer. The image inside the page scales to fit within the margins, preserving aspect ratio. If you pick Auto, the PDF takes whatever pixel dimensions the image had; the physical print size then depends on the DPI the printer interprets, which varies.
Yes. Up to 50 files per batch, 40 MB per file. The same page size, orientation, margin, and alignment settings apply to every file, which is exactly what you want when converting a folder of receipts or photos to A4 PDFs in one pass. Each image becomes its own single-page PDF; the batch is returned as a ZIP of 50 PDFs, not a single multi-page document. ZIP archives are unpacked server-side and each entry counts against the same 50-file limit.
No. Files stream to the PDF endpoint, decode into a memory buffer, get composited into a PDF, and return in the response. Nothing is written to disk, indexed, logged, or cached. The buffer is released as soon as the response is sent. The tool requires no registration and does not track which images you have converted to PDF.
