Convert Image Tools
Convert images between JPG, PNG, WebP, HEIC and PDF — free and in your browser.
Image formats are not interchangeable, and picking the wrong one costs you either quality or megabytes. JPG throws away detail to stay small and cannot do transparency. PNG keeps every pixel exactly and supports transparency, which makes it perfect for logos and screenshots and wasteful for photographs. WebP does both jobs at roughly 25-35% smaller file sizes, but a handful of older apps still refuse it. HEIC is what your iPhone shoots by default, and almost nothing outside Apple's ecosystem opens it. The tools below move a file from whichever format it is in to whichever one you actually need.
Which converter do you need?
- HEIC to JPG
- You AirDropped photos off an iPhone and Windows, a web form, or your printer refuses to open them.
- PNG to JPG
- A screenshot or export is several megabytes and you need to email or upload it. Expect a 5-10x size drop.
- JPG to PNG
- You need a lossless copy to edit further, or a format an upload form specifically demands.
- WebP to JPG
- You saved an image from a website and Photoshop, Word or an older phone will not open it.
- JPG to WebP
- You are putting photos on a website and want the same picture at a noticeably smaller size.
- Convert Image
- You want to pick the target format yourself instead of using a fixed one-way converter.
- Favicon Generator
- You need the small square icon that shows in a browser tab, built from an existing image.
- Remove EXIF Data
- You are about to publish a photo and do not want the GPS coordinates and camera serial riding along.
- Image to Base64
- You want to paste an image directly into CSS, HTML or a JSON payload instead of hosting a file.
Converting to JPG loses data — converting back does not restore it
JPG is a lossy format: it compresses by discarding detail your eye is unlikely to miss, and that detail is gone for good. Turning a PNG into a JPG and then back into a PNG gives you a PNG-sized file containing JPG-quality pixels — the worst of both. So convert in the direction you actually need, and keep the original if there is any chance you will edit the image again later. The same logic applies to repeated saves: every extra round trip through JPG softens edges and adds blocky artefacts around text and sharp lines.
Transparency survives some conversions and not others
PNG and WebP can store transparent pixels; JPG cannot. Convert a logo with a transparent background to JPG and the transparency has to become something — usually white, sometimes black. If you need the file smaller but the transparency has to stay, convert to WebP instead of JPG, or compress the PNG rather than changing its format.
Why converting here does not upload anything
Every converter on this page runs in your own browser using the Canvas and WebCodecs APIs that ship with Chrome, Safari, Firefox and Edge. Your file is read from disk into the page, converted in memory, and handed back as a download. It is never sent to a server, which means there is nothing to delete afterwards, no queue to wait in, and no file size limit beyond what your own device can hold in memory. It also means the tools keep working on a plane with the tab already open.
Frequently asked questions
Which format should I use for photos on a website?
WebP if you can, JPG if you need maximum compatibility. WebP typically saves a quarter to a third of the file size at visually identical quality, and every browser released in the last five years supports it.
Will converting reduce my image quality?
Converting to PNG or WebP-lossless keeps every pixel. Converting to JPG or lossy WebP re-encodes the image and discards some detail — usually invisible at normal quality settings, but it accumulates if you convert the same file repeatedly.
Can I convert several images at once?
Yes. Drop in multiple files and each is converted and offered as a separate download. Because the work happens on your own machine, a large batch is limited by your device's memory rather than by an upload quota.
Does converting remove EXIF metadata?
Sometimes, as a side effect, but do not rely on it. If stripping location and camera data is the point, use the dedicated Remove EXIF Data tool, which is built to do exactly that.
