About Image Converter
Cameras and websites adopt newer image formats faster than other software catches up. An iPhone shoots HEIC, web pages hand out WebP and AVIF, scanners produce TIFF or BMP, and logos often come as SVG, yet the insurance portal, the print shop and a coworker’s laptop still ask for a JPG or a PDF. This converter accepts any combination of HEIC, HEIF, WebP, AVIF, JPG, PNG, GIF, BMP, TIFF and SVG in one batch and turns all of it into JPG, PNG or one combined PDF.
Behind the drop zone, each format goes to a decoder suited to it. HEIC and HEIF are read by libheif compiled to WebAssembly, a download of about 1.4 MB that happens once, the first time you add such a file. WebP, AVIF, GIF and BMP use decoders your browser already ships. TIFF goes through a small JavaScript decoder that converts every page of a multi-page file, and SVG is drawn by the browser and rasterized at up to 4,000 px on its long edge, which means its vector shapes become ordinary pixels.
Converting starts the moment files arrive and is spread across background workers, so the page keeps responding while a long batch runs. A single run accepts up to 500 files, with no watermark, no sign-up and no daily limit.
How to use Image Converter
- Drop in the imagesDrag files or an entire folder onto the converter, click to browse, or paste an image from the clipboard. Different formats can sit side by side in the same batch.
- Pick JPG, PNG or PDFFor JPG, set the quality between 50 and 100, with 92 as the starting point. Any output can be capped at 4096, 2560, 1920 or 1280 px on its long edge, and PDF adds choices for page size and page order.
- Download the resultsSave each file separately or press Download all (ZIP); PDF mode hands you one document with a picture per page. Change a setting later and Apply new settings re-runs the batch with it.
When people use it
Emptying a phone’s camera roll
You copied a few hundred iPhone pictures, Live Photos included, into a folder. Drop the folder in and choose JPG: the stills come back with their dates intact, and the short .MOV clips are passed over.
A folder of mixed web downloads
Reference images collected over a week ended up as WebP, AVIF and PNG. One pass turns the lot into JPG so your word processor or slide software accepts every file.
Supporting pages for a claim
Receipts photographed on a phone, a TIFF from the office scanner and a PNG screenshot can go into one PDF, sorted by the date each was captured, ready to attach to an insurance or expense claim.
JPG, PNG or PDF: picking the output
| Output | Best for | Transparency | Photo info (EXIF) |
|---|---|---|---|
| JPG | Photos to share, upload or print; smallest files | Filled with white | Kept by default |
| PNG | Screenshots, graphics, cutouts, further editing | Kept | Kept by default |
| Sending several pictures as one document | Filled with white | Left out |
Dates, location, color and the ZIP
- EXIF survives. Date taken, camera, lens and GPS fields are copied into each JPG or PNG, so a photo library can still order pictures by when they were shot. The orientation tag is reset, since the pixels are already upright.
- Location can go. Tick Remove GPS location before sharing publicly; the GPS section is deleted while the date and camera details stay. Unticking Keep photo info removes all of it.
- iPhone color is preserved. HEIC photos keep their Display P3 color profile, so saturated reds and greens don’t fade when viewed on a good screen.
- The ZIP keeps shooting order. Every file in the archive is timestamped with its capture time, so sorting the unzipped folder by date modified lines the pictures up as they were taken.
Building one PDF from many pictures
By default the PDF option produces a single document with one picture per page; you can switch to one PDF per image instead. Page size can be US Letter (the default), A4, or Fit to photo, where each page matches its picture. Letter and A4 pages get 0.5-inch margins and turn portrait or landscape to suit each image. Pages follow the date taken unless you prefer file name or the order you added them; changing size or order needs no reconversion.
Inside the PDF, every picture is stored as a JPEG: the quality slider applies and transparent areas become white. Unless you choose a size, images are scaled to 2,560 px on the long edge, about 300 dpi on a Letter page. If you need upright JPGs embedded byte for byte, use JPG to PDF instead. Afterwards, Merge PDF can join it with other documents and Compress PDF can shrink it for email.
Limits and when to reach for something else
- HDR photos come out at standard dynamic range, and animated GIF, WebP or AVIF files give a single still frame.
- An SVG becomes a fixed-size raster image, so keep the original wherever a scalable logo is needed.
- AVIF needs a current browser; an outdated one marks the file as failed and asks you to update. Supported browsers are current Chrome, Edge and Firefox plus Safari 16.4 and later, iPhone and iPad included.
