Image Format Converter
Convert images between JPG, PNG, WebP, GIF and BMP online free — batch support included. Runs entirely in your browser — nothing uploaded.
An image format converter re-encodes a picture into a different file type without changing its pixels. Drop one image and this one converts it to JPG, PNG or WebPinstantly — no upload, no sign-up, no watermark. Everything runs in your browser, so the file never leaves your device.
Convert an image in three steps
- Drop one image into the box, or pick it from Google Drive. Conversion starts on its own — there is no Convert button.
- Choose the target format. Switching between JPG, PNG and WebP re-encodes immediately so you can compare the resulting sizes.
- Download. The result panel shows the new size and the percentage change against the original, with a preview above the button.
Which output format should you pick?
The choice is a trade between compatibility, transparency and size, and the right answer depends entirely on where the file is going:
- JPG — lossy, no transparency, opens absolutely everywhere. The default for photographs, email attachments and any portal or form that demands a JPEG. Quality is adjustable from 30% to 100% in 5% steps, defaulting to 90%.
- PNG — lossless with full alpha transparency, and the quality slider disappears because there is nothing to trade. Right for logos, screenshots, line art and anything with sharp edges or text. Expect a much larger file than JPG for a photo.
- WebP — typically 25–35% smaller than JPG at comparable quality, with transparency support, and supported by every current browser. The best default for the web unless you need a file that opens in older desktop software.
One thing to know about WebP here: the quality slider is only shown for JPG. WebP is encoded at whatever quality value is currently set — 90% unless you moved the slider while JPG was selected — so if you want a specific WebP quality, set it on JPG first, then switch.
Transparency, and the white box problem
Converting a transparent PNG to JPG is where most converters quietly ruin an image. JPEG has no alpha channel, so the transparent pixels must be filled with something, and a converter that fills them with black turns a clean logo into a dark rectangle. This tool flattens to white by defaultand puts a black option beside it, which matters when your logo artwork is light-coloured. Choose PNG or WebP as the target and the alpha channel is preserved untouched.
What the conversion does and does not change
| Property | After conversion |
|---|---|
| Pixel width and height | Identical — no resampling |
| File size | Changes; the result panel shows the percentage |
| Transparency | Kept for PNG/WebP, flattened for JPG |
| EXIF, GPS and camera metadata | Dropped — canvas re-encoding discards it |
| Colour profile | Converted to the browser's working space, typically sRGB |
| GIF animation | Lost — first frame only |
| SVG vectors | Rasterised at intrinsic size |
The metadata row is often the reason people convert in the first place: stripping EXIF removes the GPS coordinates, camera serial and timestamp before you post a photo. If that is the goal, theEXIF remover does it deliberately and tells you what it found.
How it compares to cloud converters and desktop apps
| ToolJiffy | Typical online converter | Desktop editor | |
|---|---|---|---|
| File leaves your device | No | Yes, uploaded | No |
| Sign-up | No | Often for larger files | Licence or account |
| File-size limit | Your device memory | Commonly 100MB–1GB free tier | None practical |
| Watermark | Never | Sometimes on free tiers | No |
| Batch and ZIP output | No — one at a time | Usually, behind a limit | Yes |
| Works offline | Yes, once loaded | No | Yes |
| Price | Free, unlimited | Free tier then paid | Paid |
When to use a different tool
This converter is deliberately one file at a time so you can watch the size change as you adjust quality. For a whole folder converted together and returned as a single ZIP, theall-in-one file converter takes multiple selections. If you need a specific format pair with its own guidance, there are dedicated pages forPNG to JPG, JPG to WebP,WebP to PNG and HEIC to JPG — the last one matters because iPhone HEIC files will not decode in Chrome or Firefox here.
Converting is also the wrong tool for two common jobs. To hit a target file size, use theimage compressor, which searches for the quality that lands under your ceiling. To change dimensions, use the image resizer — format conversion never touches width or height. And to reframe rather than re-encode, theimage cropper keeps full resolution inside the crop.
Frequently Asked Questions
How do I convert an image to another format online for free?
Drop one image into the box above and it converts straight away — there is no Convert button to press. Pick JPG, PNG or WebP as the target and the file is re-encoded instantly in the tab, then the Download button saves it with the correct extension. No sign-up, no watermark, no upload.Which input image formats does the converter accept?
Anything your browser can decode: JPG, PNG, WebP, GIF, BMP and SVG all work reliably. HEIC and HEIF are offered too, but only Safari decodes them natively — in Chrome, Edge or Firefox you will get a read error, so use the dedicated HEIC to JPG tool instead.Which output formats can I convert to?
Three: JPG for maximum compatibility and small photos, PNG for lossless quality with transparency intact, and WebP for the best size-to-quality ratio on the modern web. The chosen format is applied by the browser’s own encoder, so the download always carries a matching MIME type and extension.Can I convert multiple images at once in a batch?
Not here — this tool handles one image at a time so you can tune quality and see the result immediately. For a folder of images converted together and delivered as a single ZIP, use the all-in-one file converter, which accepts multiple selections and zips the output.What happens to transparent backgrounds when converting to JPG?
JPEG has no alpha channel, so transparency has to be filled with a solid colour. The tool flattens it to white by default and offers a black option next to the quality slider. Convert to PNG or WebP instead if you need the transparency preserved.Does converting change the pixel dimensions or resolution?
No. Width and height come through untouched — the image is drawn onto a canvas at its exact source size and re-encoded, so a 4000×3000 photo stays 4000×3000. Use the image resizer if you actually want to change dimensions, or the compressor to hit a file-size target.Why did my animated GIF or SVG lose something?
Both get flattened. An animated GIF is decoded as a single still frame, so only frame one survives; an SVG is rasterised at its intrinsic size, becoming fixed pixels that no longer scale cleanly. That is a limit of canvas encoding, not a bug — keep the original file if you need the animation or the vector.Is the converter really free and private?
Yes. Decoding, canvas rendering and encoding all happen inside your browser using built-in web APIs, so the image never reaches a server — the page keeps working with your connection off once loaded. Unlimited conversions, no account, no watermark, no file-size ceiling other than your device memory.
