Image Converter — WebP to PNG, PNG to JPG, Free & No Upload
Convert any image format free in your browser — no upload, no sign-up, no watermark. WebP to PNG, PNG to JPG, JPG to WebP: whatever the form, the printer or the app demands, this page converts it on your own device in seconds, one file or a whole batch at once.
Free Image Converter
Drop your PNG, JPG or WebP images below, pick an output format and settings, and download converted files that open anywhere.
Exact size mode always saves JPG, so the format choice is locked while it is on.
PNG is lossless, so the quality slider does not apply to it.
Fills transparent areas when the output is JPG or WebP (they have no transparency). PNG output keeps transparency as it is.
Resize only ever shrinks an image to fit inside your max width and height — it never upscales, so small images stay sharp.
🔒 Your files never leave your device — conversion happens 100% in your browser. No upload, no server, no sign-up. Browsers decode PNG, JPG and WebP natively, so there is nothing to install.
How to Convert Images (3 Steps)
- Add your images. Drag and drop one file — or a whole batch — into the box above. You can also tap to browse, or paste images straight from your clipboard. PNG, JPG and WebP files are all welcome.
- Choose a format and settings. Pick PNG for lossless quality and transparency, JPG for the smallest widely-compatible files, or WebP for modern web use. Adjust quality, background colour and max size if you need them, or switch to Exact size mode and pick 200KB, 100KB or 50KB.
- Download. Save each converted image with its own download button, or grab everything at once with Download All (ZIP).
Why Use This Image Converter?
- Batch conversion with no file cap. Most converters stop you at a handful of files or make you pay for a batch. Here you can convert a whole folder of images in one go and take it home as a single ZIP.
- Exact KB target mode. Need an image under 200KB for a visa, exam or job form? The tool tests quality levels — and shrinks the image if it must — until the file fits your limit at the best possible quality. It is the same target-size engine as our Image Compressor, and it also powers our HEIC to JPG Converter.
- Background colour control. Logos and screenshots with transparent backgrounds turn into ugly black boxes when converted to JPG by careless tools. Here you choose the fill colour — white for documents, black for dark designs — before you convert.
- Resize while you convert. Set a max width or height and the image is scaled down to fit, never stretched up. One pass gives you the right format and the right dimensions.
- Private by design. Conversion runs on your device, using your browser's own image decoder. Nothing is uploaded, stored, or seen by anyone, and closing the tab removes everything.
- Free, properly free. No account, no watermark, no "pro" unlock standing between you and a finished conversion. It works on Windows, Mac, Android, iPhone and Chromebook — anything with a modern browser.
PNG vs JPG vs WebP: What Is the Difference?
Three formats cover nearly every image you will ever meet, and they are not interchangeable. The table below is the whole story at a glance.
| PNG | JPG | WebP | |
|---|---|---|---|
| Full name | Portable Network Graphics | Joint Photographic Experts Group | Web Picture (Google) |
| Typical file size | Large — often several times a JPG of the same photo | Small — the classic compact photo format | Smallest of the three for photos, often 25–35% smaller than JPG |
| Quality | Lossless — every pixel preserved exactly | Lossy — some detail is discarded to save space | Lossy or lossless — your choice, both supported |
| Transparency | Yes, full alpha channel | No — transparent areas need a background colour | Yes, full alpha channel |
| Best for | Logos, screenshots, graphics with text, anything needing transparency | Photos, and anywhere compatibility matters most | Website images where small files and modern browsers are the priority |
Rule of thumb: PNG when quality or transparency is non-negotiable, JPG when a file must open absolutely anywhere, WebP when you control the website and want the smallest file.
Which Format Should I Choose?
It depends on where the image is going. A photo headed for a job portal, a visa form or a printer? JPG, at quality 90 — it will open everywhere and stay small. A logo, an icon or a screenshot with text? PNG, because JPG's compression smudges sharp edges and text, while PNG keeps them crisp. An image for your own website, where page speed affects ranking? WebP, which is smaller than JPG at the same visible quality and is now supported by every modern browser.
One conversion deserves a warning: turning a JPG into a PNG does not restore quality. JPG already discarded detail when it was saved, and PNG faithfully preserves the JPG — artefacts included — just in a much bigger file. Convert JPG to PNG only when you need transparency handling or a lossless master for editing, not to "improve" a photo. Going the other way, PNG to JPG, is where the quality slider earns its keep: 90 looks identical to the original for normal photos, 80 is fine for the web, and anything below 60 starts to show visible damage.
Converting Images on Windows, Mac and Phone
The converter above is the fastest route on all three, because it needs no install and handles batches. Windows users often discover this problem the hard way: a downloaded WebP image will not open in an older photo viewer, and Paint's "Save as" only handles one file at a time. Dropping the files here converts a whole set to PNG or JPG in one pass.
On a Mac, Preview converts one image at a time through File → Export, which is fine for a single photo and tedious for fifty. On a phone, the situation is worse — most gallery apps offer no format conversion at all, and the app-store converters tend to be ad-filled, watermarked, or capped at a few conversions a day. This page runs the same way in a phone browser as on a desktop: add files, choose a format, download. If you only need to shrink a photo rather than change its format, our Image Compressor does that job, and if your photos come from an iPhone in HEIC format, the HEIC to JPG Converter handles those.
Frequently Asked Questions
Is this image converter really free?
Yes. There is no sign-up, no watermark, no daily limit and no paid tier. You can convert one image or a hundred, in PNG, JPG or WebP, and download them individually or as a ZIP — all free, in your browser.
Are my images uploaded to a server?
No — never. Conversion runs entirely on your own device, using your browser's built-in image decoding and canvas tools. Your files are not uploaded, stored, or visible to us or anyone else, and closing the tab removes everything.
Can I convert an image to an exact size, like under 200KB?
Yes. Switch the tool to Exact size mode, choose the 200KB, 100KB or 50KB preset — or type any KB limit — and the converter tests quality levels, shrinking the image only if it must, until the file lands at or under your target. Exact-size mode always saves JPG so the result opens everywhere.
Can I convert many images at once?
Yes — batch conversion is the whole point. Add as many PNG, JPG or WebP files as you like; each one is converted in turn with its own preview, before-and-after sizes and download button. When two or more are ready, a Download All (ZIP) button appears so you can save the full set in one click.
Will I lose transparency when converting to JPG?
Yes — JPG has no transparency channel, so see-through areas must become a solid colour. That is what the background colour control is for: pick white for documents and forms, black for dark designs, or any custom colour before converting. If transparency matters, choose PNG or WebP output instead — both keep it.
Does converting WebP to JPG or PNG lose quality?
Converting WebP to PNG loses nothing, because PNG is lossless — it preserves every pixel of the decoded image. Converting WebP to JPG re-encodes the image, so a tiny amount of detail is discarded, but at the default quality of 90 the difference is invisible in normal photos. Avoid converting the same file back and forth repeatedly, as each JPG save adds a little more loss.
