File4Edit

Image converter

Convert images between JPG, PNG, WebP, GIF, BMP, ICO and other formats for free, right in your browser, with no upload. It opens AVIF, HEIC, SVG, TIFF and PDF files too, so almost any image can become one you can use.

Pick a target format. Quality applies to the lossy formats; the others are exact.

In detail

Convert is the plainest job on the site: one image in, the same picture out in another format. It writes PNG, JPEG, WebP, GIF, BMP, ICO, ICNS, QOI, TGA, PPM, PGM and PBM. As sources it also opens AVIF, HEIC, SVG, TIFF and the first page of a PDF.

What changes depends on the target. JPEG and WebP are lossy, so they get a quality slider; the rest are written exactly. JPEG, BMP and the Netpbm formats have no transparency, so transparent areas take a background color you pick, and GIF keeps only fully transparent pixels, blending soft edges onto that color. Safari and browsers on iPhone and iPad cannot write WebP themselves, so there File4Edit writes it with its own encoder, downloaded the first time you choose WebP. To make a file smaller rather than change its format, use Compress image.

Image converter at a glance

Input
JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, ICO, TIFF, SVG, QOI, TGA, PPM, PGM, PBM, and the first page of a PDF

What it does
  • Batch conversion with one ZIP download
  • Quality control for JPEG and WebP
  • Background color for formats without transparency
  • Filename patterns with size and index tokens
  • Formats this browser cannot write are disabled with the reason shown
  • Works offline once you have used it online
Who it is for
Anyone with an image in the wrong format for a website, an app, an upload form or an older program.
Limits
  • AVIF files open, but no browser's built-in encoder can write AVIF and File4Edit has no AVIF encoder of its own, so it cannot be chosen as an output.
  • In Safari and on iPhone and iPad, WebP is written by File4Edit's own encoder, which downloads the first time you choose WebP, so that first file takes a moment longer.
  • GIF output keeps fully transparent areas but blends soft edges onto a solid background, and an animated GIF is converted from its first frame.
  • A PDF gives its first page only; use PDF to image for every page.
Privacy
Runs entirely in your browser: no file is uploaded, and nothing is kept after you close the tab.

How to convert an image

  1. Add your images Drop files onto the page, paste one from the clipboard, or browse for them. Each file gets its own row in the queue with its size and dimensions.
  2. Pick the target format Choose PNG, JPEG, WebP, GIF, BMP, ICO or one of the specialist formats. Any format this browser cannot write is shown disabled, with the reason, rather than failing later.
  3. Set quality or a background For JPEG and WebP, drag quality between 0.05 and 1.00 (it starts at 0.82). For formats with no transparency, pick the color that transparent areas will be filled with.
  4. Adjust the filename pattern The filename field takes the tokens {name}, {width}, {height}, {ext} and {index}, so a batch can be named by its output size.
  5. Apply and download Press Apply, then download. A single file saves directly; several arrive as one ZIP.

Image converter: common questions

Are my images uploaded to a server?

No. Decoding, conversion and encoding all happen in Web Workers inside your own browser tab. The file never leaves your device, there is no account, and the tool keeps working offline once you have used it online.

Can I convert HEIC photos from my iPhone?

Yes. HEIC photos open in every modern browser, so you can convert them to JPG or PNG here on Windows, Mac, Android or iPhone. File4Edit reads HEIC but does not write it.

Can I convert an image to AVIF?

Not in any current browser. File4Edit opens AVIF files, but no browser's built-in encoder can write AVIF yet and File4Edit has no AVIF encoder of its own, so the option is disabled rather than quietly handing back a different format. WebP is the closest alternative.

Can I convert to WebP on an iPhone or in Safari?

Yes. Safari, and every browser on iPhone and iPad, can display WebP but cannot create it from a web page by itself, so File4Edit writes WebP there with its own encoder, which runs in your tab and is downloaded the first time you choose WebP. That first file takes a moment longer than in Chrome, Edge or Firefox, and nothing is uploaded.

What happens to transparency when I convert a PNG to JPEG?

JPEG has no alpha channel, so transparent areas are filled with a background color you choose, and the page says so before you convert. The same applies to BMP, PPM, PGM and PBM. GIF keeps fully transparent areas but not soft edges, which are blended onto that background color, so choose PNG or WebP for anything partly transparent.
