Most Indian application portals accept a PDF and nothing else, while everything you have is photographs from a phone. This converter turns those photos into a single PDF with a proper page size, so the result prints correctly and does not arrive as a wall of oddly-shaped images.
Your images never leave your device. They are read by your browser, drawn onto a canvas and written into a PDF in memory. Nothing is uploaded and nothing is stored.

What the JPG to PDF does
Each image becomes one page. With a fixed page size such as A4, the image is scaled to fit inside the margins and centred, preserving its proportions — nothing is stretched. With "fit the page to each image", the page takes the image's own dimensions, giving borderless pages of varying size.
Order matters when the photos are pages of a document, so the file list is numbered and reorderable before you convert.
How to use this tool
- Select your JPG photos, or drag them in. Add as many as you need.
- Check the order in the list and use the arrows to rearrange.
- Choose a page size. A4 portrait is right for almost all Indian paperwork.
- Set a margin — 10 mm is a safe default that every printer can handle.
- Press Create PDF and download the result.
How images are placed on the page
For a fixed page size:
Available width = Page width − 2 × margin
Available height = Page height − 2 × margin
Scale = min(Available width ÷ image width,
Available height ÷ image height)
The image is drawn at that scale, centred on the page.
Because a single scale factor is used for both axes, proportions
are always preserved — an image is never stretched to fill.
A4 at 72 points per inch = 595 × 842 points.
Worked example
Example: four photos of a document
| Input | 4 phone photos, about 3 MB each |
| Page size | A4 portrait, 10 mm margin |
| Quality | 92% |
| Output | 4-page A4 PDF, roughly 1.5–2.5 MB |
The PDF is usually smaller than the sum of the photos, because images are scaled to the page and re-encoded at the quality you chose.
What your result means
File size is driven almost entirely by the quality setting. If a portal has a size limit, drop quality to 75–80% before reaching for a compression tool.
A4 portrait is the safe choice for Indian paperwork. "Fit" produces a tidier-looking document on screen but pages of inconsistent size, which prints badly.
If an image looks small on the page, it is portrait content on a landscape page or vice versa. Switch the orientation.
Important considerations
- Photograph documents straight on, in even light, with the page filling the frame. Cropping before converting produces a far better result than any setting here.
- Set your phone camera to the highest quality but avoid portrait mode, which blurs the edges of a document.
- If the PDF must stay under a size limit, reduce quality first — it affects size far more than page size does.
- For photographs of a document that should look scanned, a document-scan workflow that adds contrast and greyscale processing is a better fit.
- For passport photographs specifically, size them in millimetres rather than fitting them to a page.
Limitations of this tool
- Images larger than 3000 pixels on their longest side are scaled down to that size before embedding. This keeps memory use manageable on phones and rarely affects print quality, since 3000 pixels is roughly 250 DPI across a full A4 page.
- All images are re-encoded as JPEG inside the PDF. This is what allows PNG and WebP to be embedded reliably, but it means PNG transparency is flattened onto a white background and lossless PNG becomes lossy.
- Very large batches — more than about fifty photographs — can exhaust memory on a phone. Convert in smaller groups and merge the results.
Frequently asked questions
How do I convert multiple JPGs into one PDF?
Select them all at once, or drag them in together. Each becomes a page, in the order shown in the list — use the arrows to change it before converting.
Are my photos uploaded anywhere?
No. They are read by your browser and written into a PDF in memory. Nothing is transmitted, which matters when the photos are of identity documents.
Why is my PDF smaller than my photos?
Images are scaled to fit the page and re-encoded at the quality you selected. A 4000-pixel-wide photo does not need to stay that large to fill an A4 page at print resolution.
Can I choose the page order?
Yes. The file list is numbered, and the up and down arrows change the order before you convert.
What quality setting should I use?
92% is a good default. Drop to 75–80% if you need a smaller file; below about 70%, compression artefacts become visible on photographs of text.
