Image Format Converters
Convert between every common image format — JPG, PNG, WebP, GIF, BMP, SVG, and HEIC — directly in your browser. No upload, no sign-up.
JPG (JPEG) is a lossy compressed format great for photos, while PNG uses lossless compression and supports transparency. Converting from JPG to PNG gives you an editable, pixel-perfect copy that you can layer, mask, or annotate without further quality loss.
PNG files are lossless and often huge — especially screenshots and exports from design tools. Converting to JPG dramatically cuts file size for photos and uploads where you don't need transparency.
WebP is Google's modern image format that typically produces 25–35% smaller files than JPG at the same perceived quality. It's supported by every modern browser and ideal for speeding up web pages.
WebP supports the same lossless transparency as PNG but with much better compression. Logos, icons, and UI screenshots that were 500 KB as PNG often drop under 100 KB as WebP — with pixel-identical output.
Some apps, marketplaces, and older image viewers still don't accept WebP. Converting to JPG produces a universally compatible photo file that opens everywhere — Word, eBay, government portals, you name it.
Need to edit a downloaded WebP in a tool that doesn't speak WebP? Converting to PNG gives you a lossless copy with full transparency — perfect for Photoshop, GIMP, Figma imports, or PowerPoint slides.
GIF is an old palette-based format limited to 256 colors per frame. Converting to PNG gives you a static, full-color image of the first frame — useful when you only need a still preview or thumbnail.
Turn the first frame of a GIF into a compact JPG that's easy to email, embed, or upload anywhere. Great for grabbing a still from a screen recording GIF or capturing a thumbnail of an animation.
BMP (bitmap) files are uncompressed and can be 10–50× larger than the same image as JPG. Converting to JPG makes them shareable by email, attachable to forms, and quick to load on the web.
PNG gives you the same lossless fidelity as BMP but with proper compression, so files are typically 2–5× smaller. It's the right modern replacement for BMP whenever you need pixel-perfect images.
SVG is a vector format that scales infinitely, but many tools (PowerPoint, email clients, marketplaces, app stores) need a rasterized PNG. This converter renders your SVG to PNG at its native size with full transparency.
HEIC is the high-efficiency format iPhones use by default. It's compact, but Windows, older Android phones, web forms, and many editors still can't open it. Converting to JPG produces a photo file that opens everywhere.
When you need to edit, annotate, or layer an iPhone photo without further compression, PNG is the safer choice. This converter decodes HEIC and re-saves it as lossless PNG, all locally in your browser.

Which image format should you convert to?
Format choice follows content, not preference. JPEG's compression was designed for photographs, where detail is continuous and slightly noisy, and it handles hard edges badly — text and line art pick up visible ringing. PNG is lossless with a full alpha channel, which makes it right for logos, screenshots, diagrams and anything needing transparency, at the cost of large files for photographic content. WebP does both jobs: its lossy mode beats JPEG by roughly 25 to 35 percent at equivalent quality, and its lossless mode typically beats PNG by 20 to 30 percent, with transparency support in either. For the modern web, WebP is the better choice in almost every case. The reasons to avoid it are compatibility rather than quality — some email clients, older desktop software and a few content management systems still do not read it.
Generation loss and why conversion order matters
Every lossy encode discards information permanently, and the loss compounds. Converting a JPEG to WebP re-encodes data that has already been degraded, so artefacts in the source are preserved and sometimes amplified. Converting a lossy file to a lossless format repairs nothing — a JPEG turned into a PNG contains exactly the same visible artefacts in a much larger file. The practical rule is to keep a lossless master and generate each delivery copy from it in a single pass, rather than converting a delivery copy into another delivery copy. If you only have a compressed file, convert from the highest-quality version you have rather than from one already optimised for the web. The one legitimate reason to convert lossy to lossless is before editing: it stops further degradation across repeated saves, even though it cannot undo what has already been lost.
Transparency, animation and the two silent failures
Two things disappear during conversion without any warning, and both catch people out regularly. Transparency is lost whenever the destination is JPEG, because the format has no alpha channel at all. A transparent logo converted to JPEG is composited onto a solid background — white here — which becomes a visible rectangle the moment the image sits on anything else. If you need a smaller file and transparency, convert to WebP instead. Animation is lost whenever the destination is JPEG or PNG. An animated GIF or animated WebP converts to a single still frame, silently. Because most desktop image viewers display only the first frame anyway, it is easy to convert an animated file without realising it moved. Opening the source in a browser tab is the quickest way to check, since browsers play both formats natively.
Frequently asked questions
Are these converters really free?
- Yes. Every converter here is free with no sign-up, no daily limit and no watermark on the output.
Are my images uploaded anywhere?
- No. Conversion runs in your browser using the Canvas API, with heic2any for HEIC decoding. Disconnect from the internet after the page loads and the converters still work.
Which format should I convert to?
- WebP for the modern web, JPEG when you need maximum compatibility for a photograph, PNG for graphics with transparency or as an editable master.
Will converting improve image quality?
- No. Converting to a lossless format stops further degradation but cannot recover detail already discarded. Always convert from the highest-quality source you have.
What happens to a transparent background?
- PNG and WebP preserve it. JPEG cannot represent transparency, so transparent areas are flattened onto white — visible as a box on non-white backgrounds.
Do animated GIFs stay animated?
- No. Converting to JPEG or PNG keeps only the first frame. For animation, WebP or MP4 preserve motion at a fraction of a GIF's file size.
Is there a file size limit?
- No imposed limit. Images are held in your device's memory, so very large files may be slow on a low-memory device.
