How to Convert Images to PDF: JPG, PNG, WebP, BMP, and GIF

Application portals, print shops, and archives all expect PDF documents, while cameras and phones produce JPG, PNG, WebP, BMP, and GIF images. This guide shows how to bridge that gap with imgKonvert's image to PDF tool: one image becomes a one-page PDF for free, with page sizes that match paperwork standards.

What Image to PDF Does

The tool wraps your images in a standard PDF document. Each image gets its own page, in the order you queue them. Your original files stay untouched, and the download is named automatically, for example photo-to-pdf.pdf.

One rule shapes everything: one image means a one-page PDF on the free tier. Queue two or more images and you are building a multi-page PDF, which needs a subscription. The editor states this in the queue summary before you convert, so the gate is never a surprise.

Pick the Right Page Size First

Three page sizes cover every use case:

Fit keeps the exact pixel dimensions of the image. Use it for records and archives where every pixel matters.
A4 (595 x 842 pt) places the image on the international standard sheet. Use it for most paperwork outside the US.
US Letter (612 x 792 pt) places the image on the American standard sheet. Use it for US destinations.

Both A4 and Letter fit the image inside with its aspect ratio preserved, and the orientation follows the image automatically: landscape photos get landscape pages.

How to Convert an Image to PDF

1. Upload your image

Open the image to PDF tool and select a JPG, PNG, WebP, BMP, or GIF with the file picker, or drag and drop it. Free files can be up to 5 MB. iPhone HEIC photos are rejected with a clear message, so convert those to JPG first.

2. Choose Fit, A4, or Letter

Select the page size that matches your destination. Printing on standard paper calls for A4 or Letter. Archiving a screenshot at exact resolution calls for Fit.

3. Check the queue summary

Confirm the summary reads "1 image = 1-page PDF (free)". If you queued extra images, it reads "N images = N-page PDF (premium)" instead, and exporting will ask you to upgrade.

4. Download the PDF

Review the page count and file size, then download. The result opens in any PDF reader, email client, or print workflow.

Format Notes That Actually Matter

Not every input behaves the same, and knowing the differences saves rework:

JPG embeds directly with no re-encode, so JPG to PDF is the fastest path and ideal for camera photos.
PNG transparency flattens onto a white page. Check logos before downloading, and convert photo PNGs to JPG first when size matters. See PNG to PDF.
WebP is decoded and placed as a high-quality JPEG, which is exactly why WebP to PDF exists: many document systems reject WebP outright.
BMP files are uncompressed and hit the 5 MB free cap fast. Convert oversized bitmaps to JPG first, as explained on BMP to PDF.
GIF contributes only its first frame. Animation cannot survive on a static page, stated plainly on GIF to PDF.

Common Mistakes to Avoid

Sending huge scans straight in. Files over the free cap fail, so compress or resize first. A 4 MB photo makes roughly a 4 MB PDF page.
Expecting editable text. The PDF holds images only, with no OCR and no selectable words.
Merging existing PDFs. Only image files can be added, never PDF documents.
Using the wrong input format. If the file is the wrong type, convert it first, then build the PDF.

Conclusion

Image to PDF is the right call whenever the destination expects a document: applications, portfolios, printouts, and archives. Prepare the image, pick the page size, check the summary, and download. Start with the image to PDF tool, or jump straight to your format: JPG, PNG, WebP, BMP, or GIF.
