How to use the Image Converter
- 1Drag an image onto the drop zone or click to browse and select a file from your device (PNG, JPG, WebP, AVIF, GIF, BMP, ICO, TIFF, HEIC or SVG).
- 2Pick the output format from the target dropdown, for example JPG to WebP or HEIC to PNG.
- 3If you chose a lossy format (JPG, WebP or AVIF), drag the quality slider to balance file size against sharpness.
- 4Optionally set a new width or height to resize the image, leaving one field blank to keep the aspect ratio.
- 5Click Convert and let the browser process the image locally on your machine.
- 6Download the converted file, or add more images and repeat without reloading the page.
About the Image Converter
Image Converter turns one image format into another without ever sending your files anywhere. Everything happens inside your own browser tab: when you drop a file in, the tool decodes it using the browser's native image pipeline (the Canvas and, where available, the modern WebCodecs and createImageBitmap APIs) and re-encodes it to the format you pick. Because the pixels never leave your machine, there is no upload step, no queue, and no server that holds a copy of your photo. That matters for screenshots of private documents, client logos under NDA, medical images, or anything you simply do not want sitting on someone else's disk.
It converts between PNG, JPG, WebP, AVIF, GIF, BMP, ICO, TIFF, HEIC and SVG, and covers the everyday format headaches. Convert an iPhone HEIC that a website refuses to accept into a plain JPG. Shrink a heavy PNG screenshot to WebP or AVIF and cut the file size by half or more with almost no visible loss. Turn a logo into a multi-size ICO for a favicon. Flatten a TIFF scan down to something you can email.
Alongside the format switch you get a quality slider for lossy targets (JPG, WebP, AVIF) and width/height fields to resize, so you can hit an exact pixel dimension or a smaller footprint in the same pass. A useful habit: for photos reach for JPG or WebP, but for text, screenshots, and anything with sharp edges or transparency keep PNG or WebP so lines stay crisp.
A few honest limits worth knowing. SVG is a vector format, so converting a photo *to* SVG only embeds the raster inside a wrapper rather than tracing shapes, while converting *from* SVG rasterizes it at whatever size you set. HEIC and AVIF decoding depend on your browser's built-in support, which is strong in current Chrome, Edge and Safari. Nothing is installed, nothing is tracked, and you can convert as many files as you like because the work is done by your own CPU, not a metered API.
Frequently asked questions
Why can I open a HEIC photo from my iPhone here but not on some other sites?
This tool decodes HEIC using your browser's built-in image support and re-encodes it to a universally accepted format like JPG or PNG. Current versions of Safari, Chrome and Edge can read HEIC; once converted, the output opens anywhere. If a HEIC file fails to load, your browser likely lacks the decoder, and updating it or using Safari usually fixes it.
Does converting a photo to SVG make it a scalable vector?
No. SVG is a vector format meant for shapes and paths, not photographs. Converting a raster photo to SVG embeds the original pixels inside an SVG wrapper rather than tracing them into editable vectors, so it will not scale cleanly like a true vector logo. For real vectorization you need a dedicated tracing tool.
What quality setting should I use for WebP or AVIF?
For most photos a quality around 75 to 85 keeps the image looking clean while cutting file size dramatically. Drop lower only when size matters more than fidelity. For screenshots, text or line art, prefer PNG or a high WebP setting, because aggressive lossy compression smears sharp edges and small type.
Will converting a JPG to PNG make it look better or smaller?
Neither. PNG is lossless, so it faithfully stores whatever the JPG already contains, including any compression artifacts that are already baked in, and the PNG will usually be larger. PNG is the right choice when you need transparency or want to stop further quality loss, not as a way to recover detail that a JPG has already discarded.
Is there a file size or number-of-files limit?
There is no imposed cap because nothing is uploaded to a server. Your device's memory and CPU are the only real limits, so very large TIFFs or huge batches may run slowly on older machines. Since every conversion runs locally in your browser tab, you can process as many private files as you want without them ever leaving your computer.
