Images to PDF — Combine JPG & PNG into One PDF (Free, Offline)

Page size equals image size—not fixed A4

Most converters force every image onto A4, letterboxing with white margins. This tool does the opposite: each image becomes its own page at native size. A 4000×6000 photo stays that tall; a screenshot stays small. Pages have varying dimensions, which prints unpredictably—but if you want each image at exact scale, this is the tool. Choose this when you need images at their native size; choose a fixed-page converter if every page must be A4 for professional printing.

Resolution is fixed at intake—no upscaling recovers lost pixels

A PDF page is measured in points, where one point is a seventy-second of an inch, so an image placed at its native pixel size lands at roughly 72 pixels per inch. Enlarging a small screenshot to A4 looks blocky because the PDF cannot add detail that was never in the original. The practical rule for print is 150–300 pixels per printed inch: a 1200×1200 image prints cleanly at four to eight inches across. If you need higher quality, start with a larger source image.

PNG and JPEG pass through unchanged; others convert to PNG

JPEG and PNG images embed exactly as-is, keeping their original compression and quality. WebP, GIF, BMP, HEIC, and AVIF convert to PNG at intake (lossless, in your browser). This means non-JPEG formats may increase slightly in file size. A JPG stays a JPG with its compression intact; a PNG stays a PNG at its original quality.

Reorder, rotate, and delete before downloading

Drag to reorder pages, click rotate for 90°/180°/270°, or delete unwanted pages. Mix images and PDFs freely—each image becomes one page, each PDF contributes all its pages. You can add blank pages or split into one file per page (zipped). Everything stays in your browser; the only limit is your device's available memory and 100 MB per file. For JPEG-only batches, JPG to PDF covers the same ground, and Compress PDF helps if the result is too large to email.
