Image Converter
This free image converter changes your pictures between PNG, JPEG, WEBP, AVIF, GIF, BMP, TIFF, ICO and PDF right inside your browser. Drop in a single file or a whole folder, pick an output format, and download the results, including batch conversions bundled as a ZIP. It even accepts HEIC photos from your iPhone and SVG vector files as input.
Everything runs locally on your own device. Your images are never uploaded to a server, so there are no file-size caps, no sign-up, and nothing leaves your computer.
Batch converts download as ZIP. Supports SVG and iPhone HEIC/HEIF as input. Animated GIFs and HEIC bursts use the first frame only. Files never leave your device.
How to use the image converter
- Drag your images onto the drop zone, or click to browse and select one or more files. PNG, JPEG, WEBP, AVIF, GIF, BMP, TIFF, ICO, HEIC and SVG inputs are all accepted.
- Choose your target format from the dropdown, for example JPEG for sharing or WEBP for the web.
- Click convert. Everything is processed on your device, so it is fast and private.
- Download a single file, or grab the whole set as a ZIP when you convert in batch.
Which image format should you choose?
The right format depends on what the picture contains and where it is going. PNG is lossless and keeps transparency, which makes it ideal for logos, icons and screenshots with crisp edges or text. JPEG is lossy and excellent for photographs, where its smaller files matter more than perfect pixel accuracy. WEBP and AVIF are modern web formats that usually beat both JPEG and PNG on file size at similar quality, with AVIF often the smallest of all. GIF is best left to short, simple animations.
Lossless formats (PNG, BMP, TIFF) rebuild every pixel exactly but produce larger files. Lossy formats (JPEG, and lossy WEBP or AVIF) discard some detail to shrink the file, and repeated re-saving slowly degrades quality, so keep an original master copy.
| Format | Best for | Compression |
|---|---|---|
| PNG | Logos, icons, screenshots, transparency | Lossless |
| JPEG | Photographs and complex images | Lossy |
| WEBP | Web images needing small size plus transparency | Lossy or lossless |
| AVIF | Smallest modern web files at high quality | Lossy or lossless |
| GIF | Short, simple animations | Lossless, limited colours |
Converting iPhone HEIC photos and batches
iPhones save photos as HEIC by default, which many websites, older programs and Windows apps cannot open. Drop your HEIC files in and convert to JPG to get a universally compatible image you can upload or email anywhere. To process a folder of photos at once, select them all, pick your output format and download everything together as a single ZIP archive instead of saving files one by one. You can also export images into a single PDF when you need a shareable document.
Supported image formats at a glance
Beyond the everyday choice between PNG, JPEG and the modern web formats, it helps to know what the less common formats are for. The table below summarises the main raster formats people convert between, whether they keep transparency, and the job each one suits best.
| Format | Type | Transparency | Typical use |
|---|---|---|---|
| JPG / JPEG | Lossy raster | No | Photographs and complex images where small files matter most |
| PNG | Lossless raster | Yes | Logos, icons, screenshots and graphics with crisp edges or text |
| WebP | Lossy or lossless raster | Yes | Modern websites; smaller than JPEG or PNG at similar quality |
| AVIF | Lossy or lossless raster | Yes | The smallest modern web format for photos and graphics |
| GIF | Lossless, 256 colours | Yes (on/off) | Short, simple animations and very basic graphics |
| BMP | Uncompressed raster | No | Legacy Windows software; very large files, rarely used today |
| TIFF | Lossless raster | Yes | Print, scanning and archiving where maximum quality is needed |
| HEIC | Lossy raster | No | iPhone photos; convert to JPG or PNG for wider compatibility |
| ICO | Raster icon container | Yes | Website favicons and Windows application icons |
Frequently asked questions
Are my images uploaded to a server?
No. This converter runs entirely in your browser using your own device’s processing power. Your files are read locally and never sent anywhere, which is why there is no upload progress bar and no waiting on a connection. It also means there are no file-size limits imposed by a server, and your private photos stay private.
How do I convert a HEIC photo to JPG?
Add your HEIC file from an iPhone or iPad to the drop zone, choose JPEG as the output format, and convert. You will get a standard JPG that opens on any device, website or app. This is the quickest fix when a site rejects your iPhone photo or a program says it cannot read the HEIC format.
Should I use WEBP or AVIF for my website?
Both shrink files well and are supported by all modern browsers. AVIF usually produces the smallest file at a given quality, which is great for large photos. WEBP encodes faster, has slightly broader support in very old browsers, and is a safe default. For most sites, try AVIF first and fall back to WEBP if you need wider compatibility.
Will converting reduce my image quality?
Converting to a lossless format like PNG preserves every pixel. Converting to a lossy format like JPEG, WEBP or AVIF discards some detail to save space, though at high quality the difference is usually invisible. Each re-save of a lossy file loses a little more, so always keep your original as a master and convert copies from it.
Can I convert a JPG or PNG to SVG?
Not in a true sense. JPG and PNG are raster formats made of pixels, while SVG is a vector format built from mathematical paths. Converting pixels to clean vector shapes requires tracing, which works only for simple flat graphics like logos, not photographs. For a photo, the best you can do is embed the raster image inside an SVG wrapper, which does not make it scalable or smaller.
Does converting PNG to JPG remove the transparent background?
Yes. JPEG has no transparency channel, so any transparent areas are filled with a solid colour, usually white, when you convert. If you need to keep a see-through background, convert to PNG, WebP or AVIF instead, which all support transparency. Use JPG only when the image will sit on a solid background or transparency does not matter.
Which format should I use for images on a website?
For most web images, WebP or AVIF give the smallest files at good quality and are supported by current browsers, with AVIF usually the smaller of the two. Keep PNG for logos, icons and graphics that need sharp edges or transparency, and use JPG as a widely compatible fallback for photographs. Whichever you choose, keep a high-quality master copy before exporting.
What are TIFF and BMP best used for?
TIFF is a lossless format favoured for print, scanning and archiving because it preserves full detail, at the cost of large files. BMP is an old uncompressed Windows format that is even larger and rarely worth using today. For sharing online or by email, convert these heavy formats to JPG, PNG or WebP first so the files are a practical size.
