How to Convert PNG to JPG, JPG to PNG or Any Image to WebP
- Add your images. Drag them onto Drop images here or click the box to choose files. You can add up to 10 images, each up to 10 MB.
- Pick the output format. Under Convert to, choose JPG, PNG or WebP. The same format is applied to every image in the list.
- Set the quality. The Quality slider runs from 10% to 100% and starts at 90%. It affects JPG and WebP only; it is greyed out for PNG because PNG is lossless.
- Convert. Click Convert All, or the small convert button beside one image. Each row then shows the new size and a green (smaller) or red (bigger) percentage. Once every image is done, a summary shows the total size before and after.
- Download. Use the download button on each row, or Download All to save every converted file. Clear empties the list for the next batch.
The new file keeps the original name with the new extension, so holiday.png becomes holiday.jpg. The width and height stay exactly the same — this tool changes the format, not the dimensions. To change dimensions, use the social media resizer; to squeeze a file under a size limit without switching format, try the image compressor.
JPG vs PNG vs WebP: Which Format Should You Use?
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG | Lossy | No | Photos, email, upload forms that ask for JPEG |
| PNG | Lossless | Yes | Logos, icons, screenshots you will edit again |
| WebP | Lossy (lossless at 100% in Chrome) | Yes | Website images where page speed matters |
JPG opens everywhere — on any phone, in any email client and in almost every upload portal. Many online application forms in Pakistan and India, from job portals to university admissions, still accept only JPG/JPEG. PNG is lossless, ideal for transparent logos and screenshots with sharp text, but too heavy for photos. WebP gives the smallest files of the three for most images and supports transparency. Current Chrome, Edge, Firefox and Safari all display it, but some older software and upload forms still reject .webp files.
Simple rule: photo for sharing or a form → JPG. Logo, icon or anything with transparency → PNG (or WebP for a website). Images for your own website or online store → WebP.
Real Test: How Much Smaller Does Each Format Get?
We ran three 1920×1080 images through the same browser method this page uses, in Chrome on a Mac, at the default 90% quality. Sizes are shown the way the tool shows them (1 KB = 1,024 bytes).
| Original | Converted to | New size | Change |
|---|---|---|---|
| Photo, PNG, 2.6 MB | JPG | 383.3 KB | −86% |
| Photo, PNG, 2.6 MB | WebP | 323.5 KB | −88% |
| App screenshot, PNG, 173.6 KB | JPG | 154.5 KB | −11% |
| App screenshot, PNG, 173.6 KB | WebP | 77.1 KB | −56% |
| Photo, JPG, 428.2 KB | WebP | 314.9 KB | −26% |
| Photo, JPG, 428.2 KB | PNG | 3 MB | +618% |
What the numbers tell you
- A photo saved as PNG is the big win. Converting it to JPG or WebP cut it by more than 85%. Dropping the slider to 75% took the WebP version down to 147.6 KB.
- Screenshots behave differently. JPG barely helped (−11%), while WebP halved the file. Flat colours and text suit WebP and PNG far better than JPG, and JPG can add blur around letters.
- JPG to PNG makes files bigger, never better. The PNG was about seven times the size of the JPG it came from and looked the same, because detail JPG already discarded cannot be restored.
- Re-saving a PNG as PNG is not compression. The browser simply writes the pixels out again, and the result can be larger than the original (+28% for the screenshot above). The same goes for WebP at 100%: in Chrome that setting switches to lossless WebP, which kept every pixel of the screenshot identical but produced 213.5 KB — larger than the 173.6 KB original.
Your own results will differ with the picture, the quality setting and the browser, which is why the tool shows the before-and-after size for every file.
What Happens to Transparency When You Convert to JPG?
JPG has no transparency at all, and without a fill the transparent pixels would normally come out black — which ruins a logo. This tool paints a solid white background behind your image before saving it as JPG, so a transparent PNG logo ends up on white — usually what you want for documents, email signatures and forms.
When you convert to PNG or WebP, no background is added and the transparent areas stay transparent. We checked this by converting a transparent logo: the corner pixel came out pure white in the JPG and fully transparent in the PNG and WebP files.
Need a different background colour, such as your brand colour, for the JPG? The white fill is fixed in this tool, so add the colour in an image editor first and then convert. If the logo is going to become a site icon, the favicon generator takes the PNG directly and keeps its transparency.
Tips, Limits and Common Problems
- Changed the quality after converting? Images already converted keep their old result. Click the format button again (even the one already selected) to reset them, then press Convert All.
- “Download All” saves separate files. There is no ZIP; each image downloads on its own, half a second apart. If only the first one arrives, allow multiple downloads for this site in your browser.
- WebP on iPhone, iPad or Safari is not available, because Safari’s engine cannot create WebP from a canvas; the WebP button is dimmed there and tells you so. Use Chrome, Edge or Firefox for WebP output.
- HEIC photos from an iPhone are not supported and will not convert in Chrome, Edge or Firefox (workarounds are in the FAQ below).
- Other inputs. The official list is JPG, PNG and WebP, but the tool accepts any image file your browser can open. In our Chrome test a BMP and a GIF converted fine; an animated GIF becomes a single still frame.
- Files over 10 MB are refused, and the list stops at 10 images. For a large batch, convert in rounds and press Clear between them.
- Need a PDF instead? Convert your scans to JPG here, then combine them with image to PDF.
Private by Design: Your Images Stay on Your Device
There is no upload step. Your browser reads each file, draws it onto an invisible canvas at its original size and saves that canvas in the new format. The converted image is created inside the page and downloaded straight from it, so ID card scans, signed documents and family photos are never sent to our server.
A useful side effect: because every image is redrawn, the converted file does not carry the original’s metadata. We tested a JPG containing a camera name and GPS coordinates; after conversion both were gone. That makes this a quick way to strip location data from a phone photo before posting it online or sharing it on WhatsApp.
Frequently Asked Questions
How do I convert PNG to JPG without losing quality?
Add the PNG, choose JPG under Convert to, push the Quality slider to 100% and click Convert All. JPG is always a lossy format, so a tiny amount of detail is lost even at 100%, but it is rarely visible; for a pixel-perfect copy keep the file as PNG. Any transparent areas become white in the JPG.
Why did my transparent PNG get a white background?
JPG cannot store transparency, so before converting to JPG this tool paints a white background behind your image. If you need the transparent areas to stay transparent, convert to PNG or WebP instead; both keep the alpha channel.
Is WebP better than JPG?
For file size it usually is. In our Chrome test at the default 90% quality, a 1920x1080 photo came out at 323.5 KB as WebP against 383.3 KB as JPG, and WebP can also keep transparency. JPG is still the safer choice for email attachments, older software and upload forms that only accept JPG or JPEG.
Why is my converted PNG bigger than the original JPG?
PNG is lossless, so it stores every pixel exactly, while JPG throws away detail to save space. In our test a 428.2 KB JPG photo became a 3 MB PNG. Converting to PNG also cannot bring back detail that JPG compression already removed.
Can I convert HEIC photos from an iPhone?
HEIC is not one of the supported formats. Chrome, Edge and Firefox cannot decode HEIC images, so such a file will not convert there. To get JPG files from your iPhone, set Settings > Camera > Formats to Most Compatible for new photos, or export existing photos as JPEG from the Photos or Preview app on a Mac.
How many images can I convert at once?
Up to 10 images per batch, each up to 10 MB. Download All saves each image as a separate file rather than a ZIP, so your browser may ask you to allow multiple downloads.
Why does WebP output not work in Safari?
Safari, and the other browsers on iPhone and iPad that use Safari's engine, cannot create WebP images from a canvas, which is what this tool uses. The tool detects this: in those browsers the WebP button is dimmed and explains why, so you never download a fake WebP file. JPG and PNG work normally there; for WebP output use Chrome, Edge or Firefox on a computer or Android phone.
Are my images uploaded to a server?
No. Your images are read and redrawn by your own browser and the new files are created on your device; nothing is sent to our server. Because the image is redrawn, the output also drops embedded metadata such as camera details and GPS location.
