Image to PDF

Turn photos and scans into one PDF, a page per image, in the order you choose. Set a KB limit and the whole file is made to fit it.

How it works

  1. Choose the page size, orientation and margin. A4 with a small margin suits most application forms.
  2. If the portal caps the file, tick the size limit and type it, for example 100 KB.
  3. Add the images. JPG, PNG, WebP and iPhone HEIC photos all work.
  4. Put the pages in order by dragging the rows or with the arrow buttons.
  5. Press Create PDF, check the size, and download.

One PDF for a multi-page document

Many portals ask for a single PDF where you have several photos: both sides of an ID card, every page of a marksheet, or a caste certificate and its attachment. Photograph or scan each page, add them here in order, and they come out as one file with a page each.

When the limit is very small

A 100 KB PDF holds one photographed page comfortably and three or four at reduced sharpness. Cropping each photo to the paper first, with the crop tool, removes the table and background around it and leaves more of the budget for the text. For a single photo or signature that must be a JPG rather than a PDF, use compress to a KB size instead.

Questions

How do I make a PDF under 100 KB for an exam form?

Tick 'The PDF must be under a size limit', type 100 KB (or open this page from the 'PDF under 100 KB' link), add your pages and press Create PDF. Every page is re-saved as a JPEG, the whole file is measured, and the pages are squeezed again until the total is under the limit. The bar under the result shows where it landed.

Which pages lose quality when there is a limit?

The budget is shared by page area, then rebalanced: a clean scan of typed text reaches top quality with few bytes, so the room it does not need goes to the photo pages. If a page still cannot fit at a readable quality, its pixels are reduced before the quality drops further, which keeps text sharper than heavy JPEG blocks would.

Is my JPG changed when there is no size limit?

No. An upright JPEG goes into the PDF byte for byte, so there is no second round of compression. Phone photos that rely on a rotation tag, HEIC, WebP and other formats are redrawn upright and saved as high-quality JPEG; PNG, GIF and BMP stay lossless as PNG.

What is the difference between A4, Letter and Fit to image?

A4 (210 × 297 mm) is the standard for Indian, UK and most other portals; Letter (8.5 × 11 in) is the US size. Each image is centred and scaled to fill the page inside the margin. Fit to image makes every page exactly the shape of its picture, at 96 pixels per inch, which suits screenshots and pages you scanned without borders.

What does the Auto orientation do?

It turns each page to match its picture: wide images get a landscape page, tall ones a portrait page, in the same PDF. Portrait or Landscape forces one direction for every page instead.

Are my documents uploaded to make the PDF?

No. Decoding, compression and the PDF itself are made by JavaScript in this tab, using the open-source pdf-lib library. Marksheets, ID cards and certificates never leave your device.
