What is an Image to PDF tool?

An Image to PDF converter turns one or more pictures into a single PDF document, where each image becomes one page. Instead of sending a folder of loose photos or screenshots, you can produce one tidy file that opens the same way on every device. It is ideal for scanned documents, receipts, ID photos, handwritten notes, presentation slides, and photo portfolios.

This tool runs entirely in your browser using JavaScript and the HTML canvas API. Your images stay on your device and are never uploaded to a server, so you can convert private photos, identity documents, or confidential scans without worrying about third-party access.

How to make an image PDF exactly 300 KB

Many portals cap uploads at a fixed size — 100 KB, 200 KB, 300 KB or 500 KB are the most common limits for exam forms, visa applications and job portals. A 300 KB cap is generous enough for a handful of scanned pages while still keeping the file small. Choose your limit in the Target PDF Size dropdown and the converter does the rest:

  1. Split the budget

    The target size, minus the PDF structure overhead, is divided evenly between your images.

  2. Binary-search the quality

    Each image is re-encoded repeatedly at different JPEG qualities to find the highest quality that still fits its share of the budget.

  3. Shrink the pixels if needed

    If quality alone is not enough, the image is progressively downscaled through a ladder of resolutions until it fits.

  4. Verify the real file size

    The finished PDF is measured. If it overshoots, the whole job reruns with a tighter budget — up to five passes.

Tip: a 300 KB limit comfortably fits around 3–10 scanned pages at readable quality. If you need dozens of pages, expect small, lower-resolution pictures — that is a hard mathematical limit, not a bug.

How to convert images to PDF online

  1. Add your images

    Click Select Images or drag and drop your pictures into the drop zone. Previews and dimensions appear automatically.

  2. Arrange and rotate

    Drag thumbnails to set the page order. Rotate any sideways photo with the rotation buttons, or rotate everything at once.

  3. Choose page settings & target size

    Pick a page size (A4, Letter, Legal or fit to image), orientation, margin, image quality and — optionally — a target file size.

  4. Convert and download

    Click Convert to PDF. The document is generated in your browser and downloaded automatically.

Convert images to PDF on mobile

Drag-and-drop reordering is replaced by the up/down arrow buttons on each thumbnail, so you can still control the exact page order.

Frequently Asked Questions

You can convert JPG, JPEG, PNG, WebP, GIF, BMP and AVIF images. Formats other than JPG and PNG are automatically re-encoded in your browser before being placed into the PDF.

Open the Target PDF Size dropdown and choose Under 300 KB. The converter re-encodes and, if necessary, downscales each image until the finished document fits inside the limit, then verifies the real output size.

Yes. Each image becomes one page in the final PDF. Add as many images as you like and drag the thumbnails to control the page order. A 300 KB limit comfortably fits around 3–10 pages depending on resolution.

Yes. Use the rotate buttons on each thumbnail to rotate an image clockwise or counter-clockwise, or use Rotate All CW / Rotate All CCW in the side panel to rotate every image at once.

Yes. All processing happens locally in your browser using JavaScript and canvas. Your images are never uploaded to any server.

With the Original quality setting and no target size, JPG and PNG files are embedded exactly as they are with no re-compression. Target-size mode deliberately trades some quality for a smaller file — but at 300 KB there is much more headroom than at 100 KB.
