How to Convert and Download Images as JPG, PNG or WebP
Sooner or later you get an image in a format you cannot use. A website asks for JPG but you have a PNG. A photo from a phone arrives as WebP and your old software will not open it. A client sends a TIFF and you need something small enough to email.
This guide is a practical walk-through of converting images to JPG, PNG or WebP and downloading the result. It focuses on the steps, the quality slider and the mistakes to avoid. If you would rather understand why the formats differ first, see our separate guide on JPG, PNG and WebP.
Before you convert: pick the target format
Converting is easy once you know what you need. Ask yourself where the image will be used, then choose from this quick list.
- The upload form says JPG or JPEG: convert to JPG.
- You need a transparent background: convert to PNG or WebP. JPG cannot store transparency.
- You want a small file for a website: convert to WebP, or to JPG at a moderate quality.
- You need a favicon: convert a square PNG to ICO.
- You want to send the image as a document: convert it to PDF.
How to convert an image online, step by step
The Image Converter works in your browser and needs no account. Common conversions between JPG, PNG and WebP are processed directly on your device, so the image does not need to be uploaded for those.
- Open the Image Converter and click Upload File.
- Select the image from your device. A preview appears with the detected original format.
- Choose the target format from the drop-down list. The format you already have is left out automatically.
- If you picked JPG or WebP, move the quality slider to the level you want.
- Click Convert Image, then download the result.
The downloaded file keeps your original name and adds a _converted suffix, so photo.png becomes photo_converted.webp. Your original file is never changed, which means you can always go back.
What the quality slider does
When you convert to a lossy format such as JPG or WebP, a slider lets you trade file size against detail. Lower numbers give smaller files but remove more detail.
| Setting | File size | Typical use |
|---|---|---|
| 90–100% | Largest | Photos you plan to edit again or print |
| 80–85% | Balanced | Most website and blog images |
| 60–70% | Small | Thumbnails and email attachments |
| Below 50% | Very small | Previews only, artefacts become visible |
PNG is lossless, so the slider does not apply to it. A PNG conversion keeps every pixel, which is why PNG files of photos are often large.
The most common conversions
PNG to JPG
Use this to shrink a photo or to meet an upload rule. Remember that JPG has no transparency, so any transparent area will turn into a solid colour, usually white.
WebP to JPG
Handy when a program or a website does not accept WebP. Choose a quality of about 85% for a good balance between size and sharpness.
JPG to PNG
This does not improve the picture, because detail lost in a JPG cannot come back. It is useful when a platform requires PNG, or when you plan to edit and save the image many times without further loss.
PNG to WebP
A good choice for web pages. WebP files are usually smaller than PNG or JPG files of similar quality, and modern browsers display them without trouble.
PNG or JPG to ICO or PDF
ICO creates a favicon for your site, and PDF wraps an image in a document that is easy to print or attach.
Three situations where converting saves time
Preparing product photos for an online shop
Shops often set a size limit per image. Converting large PNG photos to JPG at 80–85% can cut the size dramatically while still looking sharp on a product page.
Fixing an image a form will not accept
Government and job portals frequently accept only JPG or PDF. Convert once, then upload. If the file is still too large, lower the quality slider a little and try again.
Speeding up your own blog or portfolio
Large images slow pages down. Converting to WebP and resizing to the width you actually display is one of the simplest ways to make a page load faster.
Mistakes to avoid
- Converting the same JPG again and again. Every lossy save removes a little more detail, so always convert from your original.
- Using JPG for a logo with a transparent background. Use PNG, WebP or SVG instead.
- Expecting a bigger resolution. Conversion changes the format, not the pixel size. To make an image larger, see our guide to upscaling a low-resolution image.
- Deleting the original. Keep the source file until you have checked the converted one.
Use images you have the right to use
Convert only images that you own or have permission to use. Changing a file's format does not change who owns it. Read our Copyright Policy for our approach.
Frequently asked questions
How do I convert PNG to JPG for free?
Open the Image Converter, upload your PNG, choose JPG as the target format, set the quality, and download the converted file. No account is required.
Will converting reduce the quality of my image?
Converting to a lossless format such as PNG keeps all detail. Converting to JPG or WebP removes a little detail depending on the quality setting, so keep your original file.
Which formats can I convert between?
The tool supports JPG, PNG, WebP, BMP, TIFF, GIF, ICO, SVG and PDF. The exact targets available depend on the file you upload.
Is my image uploaded to a server?
Conversions between JPG, PNG and WebP run in your browser. Some other formats, such as TIFF or ICO, are processed on the server so they can be encoded correctly.
Why does my transparent background turn white?
JPG cannot store transparency, so it fills transparent areas with a solid colour. Convert to PNG or WebP to keep the transparency.
What quality should I choose for a website?
Around 80–85% is a good starting point. Compare the result with the original and lower the number only if the file is still too large.
