How to convert images into one PDF

  1. 01

    Add your images

    Choose up to 50 PNG or JPEG files, at most 20 MiB each and 50 MiB combined. Extension, type, size, and signature are checked locally before the PDF engine loads. A damaged file can still pass the signature check and fail later when the image is embedded; a new picker selection replaces the list.

  2. 02

    Arrange the page order

    The list order becomes the page order, one image per page. Move an image up or down with the arrow controls next to its name, or remove it, until the sequence reads correctly; the running total next to the list shows how much of the 50 MiB budget the selection uses.

  3. 03

    Choose the page size

    Pick Fit to image, A4, or Letter under Page size. Fit to image sizes every page to its image, so pages can differ; A4 (595.28 × 841.89 points) and Letter (612 × 792 points) scale each image to fit the sheet, centered, without changing its aspect ratio. For anything headed to a printer or an office workflow, a fixed sheet size is the safer choice.

  4. 04

    Create and download

    Press Create PDF and save the combined document from the result panel, which reports the image count, page count, and output size. The download is named toolars-images.pdf, and resetting the workspace clears every loaded image and the previous result.

What Images to PDF actually does

Combine receipt photos or design images in the order you choose, one image per PDF page. Fit to image uses the image dimensions as PDF points; A4 and Letter keep a fixed portrait page while scaling the picture without changing its aspect ratio. Download and inspect the pages before submitting them; this tool does not straighten scans or certify that a document is ready to sign. Files stay in your browser.

Common questions

Which image formats are accepted?
PNG and JPEG only, and each file's magic bytes are verified rather than its extension. WebP, GIF, SVG, and other formats are refused with a clear message; convert them to PNG or JPEG first. A damaged file that passes the byte check but cannot be embedded is also rejected with its name attached.
What are the limits?
Up to 50 images per run, each image up to 20 MiB, and the whole selection up to 50 MiB combined. The running total is shown next to the list, and an over-limit selection is rejected before any processing.
Are the images recompressed or resized?
The tool does not resize or intentionally apply a new lossy JPEG encoding, but it embeds images through the PDF library. JPEG data can be embedded as a JPEG stream; PNG content is decoded and represented in the PDF rather than kept as the original PNG file bytes. PDF viewers may render it differently. Choose a page size, download, and inspect the result; byte-for-byte identity with the source image is not promised.
What do the three page sizes do?
Fit to image gives every page the dimensions of its image, so a document can mix page sizes. A4 and Letter keep each image's aspect ratio and scale it to fit inside the sheet, centered; portrait and landscape images can be mixed freely in one document.
Are the images uploaded anywhere?
No. The composition runs fully inside the current browser tab and the images never leave your device. No account is required, and resetting the workspace discards every loaded file.

PDF Scan Effect

Add a synthetic scan-style texture to a PDF or image locally. This visual effect is not evidence of a physical scan or document authenticity.

Convert

PDF Merger

Merge 2-12 PDFs in your chosen order — up to 50 MiB and 500 pages combined — entirely in the browser, with per-file validation.

Edit

PDF Splitter

Extract selected pages or ranges into one new PDF, in the order you choose. Files stay in your browser and the original is unchanged.

Edit

PDF Rotator

Fix sideways PDF scans by rotating all or selected pages 90, 180, or 270 degrees without rasterizing content. The PDF is saved again; byte identity is not guaranteed.
