KEMI Tools

Images to PDF (JPG / PNG → PDF)

Combine phone photos of documents, scans or screenshots into a single PDF. Set the order, place them on A4 or Letter (or size pages to the image), and pick a quality that fits upload limits. Phone rotation (EXIF) is applied so nothing ends up sideways, and every step runs in this browser with no upload.

Drop the images to turn into a PDF

JPG · PNG · WebP — select many at once · on phones, pick from your gallery or camera

How to use

Drop images into the box above or click to choose. On phones you can pick many photos from your gallery at once.
Set the order — drag on desktop, ↑↓ buttons on phones, or “Sort by name” if the files are numbered.
Straighten sideways photos with ↻ (the rotation stored by phone cameras is applied automatically).
Pick page size (A4, Letter or fit-to-image), orientation, margin and quality. For official submissions we suggest A4 · Auto · 5–10 mm · Standard.
Press “Create PDF & download” — you get one PDF with one image per page.

Photograph paper documents and submit them as PDF

Government forms, school applications, job paperwork and insurance claims often ask for “a scanned PDF”, but most people don't own a scanner. Photograph the pages with your phone and combine them here — no scanner needed.

For good results, lay the page flat on a dark desk, shoot in even light away from harsh shadows, hold the phone parallel to the paper and keep all four corners in frame. Turn the flash off to avoid glare. With A4 and Auto orientation, portrait pages land on portrait sheets and landscape pages on landscape sheets.

Staying under upload limits — choosing quality

Modern phone photos are 3–8 MB each and over 4000×3000 pixels. Ten of them easily make a 50 MB PDF that portals with a 10 MB limit will reject. That's why the default is Standard (2400 px long edge, JPEG 85%): enough for about 200 dpi on A4 so text stays sharp, while a typical photo shrinks to 0.4–1 MB.

For tighter limits choose Smallest (1600 px, 72%) — fine on screen, but check small print by zooming in. Original embeds JPG/PNG files that need no rotation without recompression, so there is zero quality loss but the largest size — good for portfolios and print.

Why photos come out sideways — EXIF orientation

Phones store pixels in the sensor's orientation and add a tag (EXIF Orientation) saying how to rotate the picture for display. Gallery apps honour it; tools that ignore it put sideways photos into your PDF. This tool asks the browser to decode images with EXIF orientation applied, so pages match what you see in your gallery. Use ↻ for photos that were genuinely shot crooked.

Transparent PNGs are flattened onto white and converted to JPEG in Standard and Smallest (some viewers render transparency as black). Original keeps PNGs as-is, transparency included.

Page size — A4, Letter or fit-to-image

A4 (210×297 mm) is standard in Korea and most of the world; Letter (216×279 mm) is used in the US and Canada. Images keep their aspect ratio and are centred as large as the margins allow. “Fit to image” sizes each page to the image itself with no white border — ideal for photo albums and screenshot collections viewed on screen.

Converted without uploading

Photos turned into PDFs are often IDs, bank statements or certificates. Nothing leaves your device: decoding, resizing and assembling the PDF all happen in your browser, the PDF is saved straight to your device, and everything is cleared from memory when you close the tab.

Privacy

The images you choose are decoded and converted only in this browser's memory and are never stored. Closing the tab clears them. The site records only an anonymous “tool used once” count — never file names or contents. Ads on this page have no access to your files.

FAQ

Does it accept iPhone HEIC photos?

HEIC support varies by browser: Safari on iPhone/Mac usually opens it, Chrome/Edge on Windows may not. If it fails, set iPhone Settings › Camera › Formats › Most Compatible, or export the photos as JPG.

Will the PDF be text-searchable?

No — images are placed in the PDF, so text is part of the picture. Use an OCR program if you need searchable text. Most portals accept image PDFs as they are.

How can I make the PDF smaller?

Choose Smallest, and crop photos to the document itself. If it's still too large, split it into several files with Split PDF.

How many images can I add?

No fixed limit. Images are processed one at a time, so dozens are fine; hundreds of high-resolution photos in Original quality may exhaust device memory.

I want to add photos to an existing PDF.

Convert the photos first, then combine with the existing PDF in Merge PDF, where you can also reorder individual pages.

Are my photos stored anywhere?

No. They are processed entirely in your browser and never transmitted.
