Universal Converter
Convert between JPG, PNG, WEBP, HEIC and PDF in either direction.
Universal File Converter — JPG, PNG, WEBP and PDF, Free, Both Directions
Every document errand eventually needs a format it did not start in — a scanned bank document that arrived as a JPG needs to become one combined PDF, a multi-page PDF certificate needs its pages saved as individual images, or a WEBP photo from a website will not upload to a form that only accepts JPG. Most single-purpose converters only handle one of these directions; this tool handles images and PDFs together, in either direction, in one page.
Drop in one file or several at once — a mix of image types and a PDF is fine — choose what you want out, and press Convert. A single result downloads directly; more than one comes back together as a ZIP, unless you chose to combine multiple images into a single PDF instead. Everything happens inside your browser, with no account and no file ever uploaded to a server.
JPG vs PNG vs WEBP vs PDF — When to Use Each
| Format | Best for | Note |
|---|---|---|
| JPG | Photographs, most government and exam form uploads | Universally accepted, compresses photos efficiently |
| PNG | Screenshots, logos, graphics needing transparency | Lossless but produces larger files than JPG |
| WEBP | Websites and apps that support it, smaller downloads | Not every older portal accepts it — check first |
| Multi-page documents, certificates, anything meant to be printed as one file | The standard format for official multi-page submissions |
Converting Images to One PDF, or a PDF Back Into Images
Turning several photos or scans into a single PDF is one of the most common document tasks — a set of Aadhaar, PAN and address-proof photos that need to travel together as one file for an application, in a fixed order. Drop them in, in the order you want them to appear, choose PDF as the output, and leave "Combine into one PDF" ticked; each image becomes its own page in that single file.
Going the other way — turning a PDF's pages into separate images — uses the "PDF page rendering" quality setting to control how sharply each page is drawn before it is saved as a JPG or PNG. Normal is fine for reading on screen; choose High or Maximum when the images will themselves be printed or need to preserve fine text detail from the original PDF.
A Note on iPhone HEIC Photos
iPhones save photos in Apple's HEIC format by default, which most non-Apple browsers cannot open at all — this is a limitation of the browser reading the file, not something a converter running inside that same browser can work around. If a HEIC photo does not appear after you choose it, the simplest fix is on the phone itself: open Settings, go to Camera → Formats, and switch from "High Efficiency" to "Most Compatible" — new photos will then save directly as JPG, which every browser and every form accepts without any conversion step at all.
Tips for a Clean Conversion
- Order your files before converting to a combined PDF — remove and re-add a file to change where it lands, since pages are combined in the order shown in the list.
- Turn quality down for PNG-heavy batches — PNG is lossless regardless of the quality slider, so that setting only affects JPG and WEBP output within the same batch.
- Use High or Maximum PDF rendering only when you actually need to print the extracted images or zoom into fine text — Normal converts faster and produces smaller files for everyday viewing.
- Convert a HEIC photo to JPG on the iPhone itself first (share it, or re-save it) if your browser cannot open it directly, then bring the JPG here for anything further.
Your Files Never Leave Your Device
Every conversion — decoding an image, rendering a PDF page, building a new PDF, zipping several results together — runs as JavaScript inside your own browser tab. Nothing is uploaded to make any of this happen, there is no account to create, and each result only leaves your device the moment you download it. Close the tab afterward and nothing of your files remains anywhere but your own device.
How to use it
- Drop in one or more files — images or a PDF.
- Choose what you want out: JPG, PNG, WEBP or PDF.
- Press Convert. Several files at once come back as a ZIP, unless you asked for a single PDF.
Questions about this tool
Can it open HEIC photos from an iPhone?
Only if your browser can decode HEIC — Safari on Apple devices can, Chrome on Android generally cannot. If nothing appears after you choose the file, set your iPhone camera to "Most Compatible" and it will save JPGs instead.
How do I turn a PDF into images?
Drop the PDF in and choose JPG or PNG as the output. Every page comes back as a separate image, zipped together when there is more than one.
How do I turn images into one PDF?
Drop the images in, choose PDF as the output, and leave "Combine into one PDF" ticked.
Does anything get uploaded?
No. Both the image work and the PDF work run in your browser.
Can I convert several files of different types in one go?
Yes — drop in a mix of JPGs, PNGs and a PDF together and pick one output format; each file is processed on its own and the results come back together as a ZIP, unless you chose "Combine into one PDF," in which case every page from every file lands in that single PDF in order.
What does the "PDF page rendering" quality setting change?
It sets how sharply a PDF's pages are drawn before being turned into images — Normal is smaller and faster, High is a good balance for printing, and Maximum produces the crispest result at the cost of a much larger file and a slower conversion. It only appears when at least one of your input files is a PDF.
Why did nothing happen when I tried to convert a PDF to a PDF?
That combination is blocked on purpose — there is nothing to convert. Pick JPG or PNG as the output when your input is already a PDF and you want its pages as images instead.
Is there a limit on how many files I can convert at once?
No hard limit is enforced, but every file is processed by your own browser and device, one after another — a very large batch of high-resolution photos or many-page PDFs will simply take longer and use more memory than a handful of files.
