One image to PDF converter for every format
This image to pdf converter takes whatever your phone or scanner gave you and builds a proper document. You can convert image to pdf from JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF and more. It works as a photo to pdf or picture to pdf tool, and it is image to pdf free, with image to pdf no watermark and image to pdf no sign up.
The PDF is made inside your browser, so it is also an image to pdf online tool that never uploads your files. For Aadhaar, PAN and marksheets, that matters: image to pdf without uploading is the safe image to pdf for documents choice.
Multiple images to one PDF
Add up to 30 pictures and choose one PDF. Each image becomes a page. This is the fastest way to merge images into pdf, or combine images into one PDF, for a form that accepts a single upload.
Mixed images to PDF, in one go
Photos to PDF does not need matching formats. An iPhone HEIC, a WhatsApp JPG and a PNG screenshot can go into the same file. Files are detected by their contents, not the extension, so a jfif or a wrongly named photo still works. WebP to PDF is covered too.
Image to PDF for exam forms and government portals
Indian application portals usually want documents as PDF with a size cap. Typical limits look like this. Always follow the notice for your form, since limits change between years. The same method works for SSC document upload PDF files, UPSC document upload PDF files and bank passbook to pdf scans.
If the portal says the pdf file size too big for form, reduce the pictures and convert again.
| Document | Pages | Common PDF limit |
|---|---|---|
| Aadhaar card | 2 (front and back) | 100-500 KB |
| 10th / 12th marksheet | 1-2 | 200-500 KB |
| Caste, income, domicile certificate | 1-2 | 100-500 KB |
| Degree and semester marksheets | several | 500 KB - 2 MB |
Image to pdf under 200kb
There is no one-click image to pdf in KB target here, so shrink each page first and the PDF follows:
- Crop each photo to the paper edge with crop.
- Resize to about 1200 px on the longest side with resize.
- Compress with Exact size to about 90 KB for each of two pages.
- Convert to one PDF with A4 pages.
Image to pdf under 100kb
One page at about 90 KB, or two pages at about 45 KB each, gives a PDF under 100 KB. Text at 1000-1200 px on the long side is still readable for most certificates.
Image to pdf 500kb or 1mb
With a bigger limit, keep more detail. Four pages at about 110 KB each fit image to pdf 500kb, and eight to ten pages fit image to pdf 1mb.
Aadhaar card to PDF: front and back in one file
Forms often ask for the Aadhaar front and back in one PDF. Here is the clean way.
- Photograph both sides on a dark, plain table in daylight.
- Crop each side tightly so no table shows.
- Add front first, then back, and choose one PDF with A4 pages.
Why do this in the browser?
Your Aadhaar number, photo and address stay on your phone, because the image to pdf private conversion never uploads anything. The same goes for pan card to pdf, voter id to pdf and driving licence to pdf jobs.
Masking what the form does not need
If you share a copy with a shop or landlord rather than a portal, you can hide details first with blur or pixelate before making the PDF.
Marksheet to PDF and certificates for admissions and jobs
Every scholarship form documents PDF, college admission documents PDF and job application documents PDF needs care. Each one should be sharp enough to read roll numbers and grades.
10th marksheet PDF and 12th marksheet PDF
Photograph the marksheet flat, with the phone held straight above it. Crop, then convert. If the portal wants each document separately, choose one pdf per image so every marksheet gets its own file.
Certificate to PDF
For a caste certificate PDF upload, income certificate PDF or domicile certificate PDF, keep one certificate per file and name it clearly, for example caste-certificate.pdf.

Self attested document PDF
Sign the paper copy, write self-attested, then photograph and convert it. The signature shows up in the PDF like on the original.
Page size, margins and page order
Choose how each page is laid out.
- Same as picture: the page matches the image, best for sharing on screen.
- A4: the image is fitted on a 210 x 297 mm page, the usual choice for Indian government forms.
- Letter: fitted on 8.5 x 11 in (image to pdf letter size), for the US and Canada.
Image to pdf same size as the picture is best for WhatsApp and email.
Which page size for government form PDF?
Pick image to pdf A4 size unless the notice says otherwise. An image to pdf with margin setting of a few millimetres makes the page look like a scan and nothing touches the edge.
Image to pdf page order
In a bulk image to pdf or batch image to pdf job of up to 30 images to pdf, pages follow the order you add files. For a long set, rename the images 01, 02, 03 before adding, or add them one at a time.
Image to pdf separate files
Choose one PDF per image when a portal has one upload box per document, then download them together as an image to pdf zip.
Notes, receipts and assignments to PDF
Documents to PDF is not only for forms. Students and small businesses use it every day.
Handwritten notes to PDF
Photograph each page, crop it, and merge into one file. Assignment photos to PDF are easier for a teacher to open than twenty loose pictures, and notes to PDF stay in order.
Receipts and bills to PDF
Turn a month of receipts to PDF for an expense claim, or bills to PDF for your accountant. Scanned images to PDF from an office scanner work the same way.
Fix common problems before you upload
Pdf too large to upload
A PDF holds each picture you add, so the image to pdf file size is roughly the total of your photos. Ten 4 MB camera photos make a 40 MB PDF. Compress or resize the photos first, as in the steps above.
Image to pdf without losing quality
Each picture is placed on its page as it is, so the PDF is as sharp as your photo.
Image to pdf blurry
Blur comes from the photo. Shoot in daylight, tap on the text to focus, and keep the phone parallel to the page. A readable document scan beats a big one.
Document photo sideways
Some phones save a turned photo with a sideways flag. Straighten it with rotate, which saves the picture upright, then convert.
Crop document photo edges
Table corners and fingers make a scan look careless and waste bytes. Crop to the paper edge before converting.
