An image converter changes a picture from one format to another: JPG to PNG, WebP to JPG, an iPhone HEIC photo to a file Windows can open. It also brings photos down to the exact KB size a form demands. On ToolPeko all of it runs in your browser, free.
Every tool below runs in your browser, on your own device. Open one, finish the job, close the tab. Nothing you use here is uploaded or stored.

Files arrive in the wrong format all the time. The iPhone hands you HEIC, the website downloads as WebP, the form accepts only JPG. Converting is the small job that unblocks the bigger one, and this page holds every pair people actually ask for.
The classic swaps: JPG to PNG when you need clean edges, PNG to JPG when you need a lighter file. The web formats: WebP to JPG and WebP to PNG for pictures a site gave you in a format your apps dislike, and JPG to WebP and PNG to WebP when you are the one building the site and every kilobyte counts. Phone photos: HEIC to JPG and HEIC to PNG turn iPhone pictures into files everything else can open, and AVIF to JPG does the same for the newest format of all. One box for anything else: Image Converter.
Icons, vectors and older formats: SVG to PNG renders vector art at the size you pick. PNG to SVG and JPG to SVG trace flat art and logos back into vectors. PNG to ICO makes icon files, GIF to JPG saves a still frame, and BMP to JPG shrinks heavy old bitmaps.
And the sizes forms demand: Compress Image to 20KB, Compress Image to 50KB, Compress Image to 100KB, Compress Image to 200KB, Compress Image to 10KB and Compress Image to 1MB hit the exact cap a portal checks. There is a JPEG-specific version too, Compress JPEG to 100KB, plus the fixed shapes: Resize Image to Passport Size, Resize Image for Social Media, Resize Signature and Split Image for grid posts.
| Your problem | Use this | Why it fits |
|---|---|---|
| My iPhone photo will not open on Windows | HEIC to JPG | JPG opens everywhere, no new apps needed |
| The site only accepts JPG and my picture is WebP | WebP to JPG | The accepted format, same picture |
| My PNG logo needs a transparent, smaller copy for the web | PNG to WebP | Much lighter, and the transparency survives |
| The form says photo must be under 50KB | Compress Image to 50KB | Aims at the exact number the form checks |
| My signature scan is too heavy for the application | Resize Signature | Sized and lightened for form uploads |
| I have an SVG logo and need a picture file | SVG to PNG | Rendered at the size you pick, edges stay sharp |
| I want one big picture as a social media grid | Split Image | Even tiles, in posting order |

On most converter sites the picture travels to a server and comes back changed. Here the conversion runs in your own browser. Your image never leaves your device, so the photo of your ID card or your child is not sitting on a stranger’s disk waiting to be deleted.
What to know before you convert:
A candidate converts an iPhone photo of his degree because the job portal has never heard of HEIC. A shopkeeper brings product photos under the marketplace size cap one by one. A designer saves a WebP hero image as JPG for a client whose old software refuses it, and a student shrinks a signature scan until the exam form finally accepts the upload. Format problems are small, but they block everything behind them.
Yes. Every converter on this page is free, with no paid plan behind it and no watermark on your pictures. ToolPeko earns from ads on the site.
No. Conversion runs inside your browser, on your own device. Your picture never travels to us, which is why conversions start at once, with no upload wait.
JPG for photos and anything that must stay small. PNG for screenshots, logos and pictures with text or transparency, where clean edges matter more than size.
iPhones save HEIC, a newer format many Windows apps still cannot read. HEIC to JPG turns them into the format everything opens.
The converters are built for quick jobs one picture at a time, which covers most form and sharing problems. That keeps them fast on phones as well as computers.
Swapping between PNG, WebP and SVG keeps the picture as it is. Saving into JPG gives up a little detail for size, and hitting an exact KB target gives up a little more.
Yes. They run in the browser on Android and iPhone, and on Windows and Mac. Converting a phone photo on the phone itself is the most common job on this page.
This is only one drawer of the toolbox. The rest work the same way: free, in your browser, with nothing uploaded.
