Convert images to PDF on your own device

What this image to PDF converter does

It turns one or many pictures into a PDF file without sending them anywhere. Most “free” converters upload your photos to a server, process them there, and keep a copy for a while. This one does the whole job inside your browser using the same engine that renders web pages, so a scan of your ID card, a signed form or a child’s school certificate stays on your phone or laptop.

You get the controls you would expect from a print dialog: page size, orientation, margins, image quality, and the choice between one combined PDF or a separate PDF for every image. The one control most tools miss is a maximum file size. Application portals in India, Pakistan, Bangladesh and Malaysia regularly reject uploads over 100 KB or 200 KB; type the limit and the converter does the shrinking for you.

How to convert images to PDF

1. Add your images. Click the sheet or drag photos onto it. You can also paste a screenshot with Ctrl+V. JPG, PNG, WebP, HEIC, GIF, BMP, AVIF and SVG all work, and you can mix formats.
2. Put the pages in order. Each image shows up as a numbered page. Drag a page to move it, or use the arrows. Rotate a sideways photo with the ⟳ button; remove one with ×.
3. Choose the page setup. Pick A4 or Letter (or “Fit to image” for no borders), portrait, landscape or automatic, and a margin. These are the same choices as a print dialog.
4. Set a size limit if a form needs one. Government portals, exam applications and visa sites often cap uploads at 100 KB, 200 KB, 500 KB or 1 MB. Type that number and the tool shrinks the PDF to fit.
5. Convert and download. Click “Convert to PDF”. The PDF downloads straight away and the final size is shown. Nothing has left your device.

Supported formats

JPG / JPEG

Phone photos and scans. Camera orientation is read from the file, so sideways shots come out upright.

PNG

Screenshots and graphics. Transparent areas are placed on white, which is what printers and viewers expect.

HEIC / HEIF

The default iPhone format. It is converted on your device first, so you don’t need to change your camera settings.

WebP and AVIF

Images saved from websites and WhatsApp. Both are decoded natively by current browsers.

GIF and BMP

Older formats still common in email attachments. For animated GIFs the first frame is used.

SVG

Vector drawings are rendered to a page-sized bitmap.

You can mix formats in one PDF. If you only have JPGs or only PNGs you may prefer the dedicated JPG to PDF and PNG to PDF pages, which use the same engine. For iPhone photos there is also HEIC to PDF.

Getting under a file size limit

A single photo from a modern phone is 3–6 MB. Converted at full quality that is far above the limits most portals set. The size box solves this in two stages: first the JPEG quality is lowered in steps (92 % → 85 % → 75 % and so on), and only if that is not enough is the resolution reduced. Text on a scanned form usually stays readable down to about 1,000 pixels on the long side, which is why a one-page scan fits in 100 KB and a two-page one in 200 KB.

If the tool cannot reach your limit it tells you, rather than silently giving you a blurry file. The fix is almost always to split the pages across two PDFs or ask whether the portal accepts a higher limit.

One PDF or one per image?

Why no upload matters

Identity documents, medical reports, salary slips and exam admit cards are exactly the files people convert most often, and they are the files that should not sit on a third-party server. Browser-side conversion removes the question entirely: there is no upload, no queue, no retention period and no account. It is also faster for most people, because a 5 MB photo does not have to travel to a data centre and back on a mobile connection.

The trade-off is that the work is done by your device, so a batch of a hundred full-resolution photos on an old phone takes a while. For documents – which is what PDFs are for – it takes a second or two.
