How to use the Image Converter

  2. 2Choose the target format (JPG, PNG, WEBP, BMP, TIFF or GIF).
  3. 3Press Convert and download your files or a ZIP of all of them.

Image formats explained: when to use JPG, PNG, WebP, AVIF, HEIC and PDF

Pictures come in many formats, and each one is good at something different. The Image Converter changes between them in a click, for a single picture or a whole folder, and keeps colours, rotation and animation intact.

Common uses

iPhone photos that will not open

HEIC is efficient but not supported everywhere. Convert to JPG so a Windows PC, a website form or an older app can open it.

Faster websites

WebP and AVIF are typically 25 to 50 percent smaller than JPG at the same quality, which cuts page weight and improves load speed.

Logos and graphics with transparency

Use PNG or WebP to keep a transparent background. JPG has no transparency, so transparent areas are placed on white.

Camera RAW files

Convert CR2, NEF, ARW or DNG to JPG or TIFF for sharing or for programs that do not read RAW.

Icons and favicons

Make an ICO or ICNS file from a square PNG for Windows, macOS or your website.

Documents and printing

Convert pictures to PDF for submission or printing, or to TIFF for professional print workflows and archives.

JPG, PNG and WebP in one minute

JPG is lossy and ideal for photographs. PNG is lossless and best for screenshots, text and transparency. WebP does both jobs more efficiently and is supported by every modern browser.

AVIF and HEIC

AVIF gives excellent quality at very small sizes and is great for websites. HEIC is what iPhones record by default. Both use modern compression, and you will usually want to convert them to JPG or WebP for compatibility.

Quality, colour and rotation

Photos taken in portrait orientation keep their correct rotation, and embedded colour profiles are preserved so colours do not shift between devices.

Animated pictures

Animated GIF and WebP stay animated when you convert between animation-capable formats.

Batches and large files

Add a whole folder at once. Each picture is converted in parallel with live progress, and big files (up to 200 MB in total) are uploaded in safe pieces.

Privacy

Only images are accepted, no account is needed, and results are deleted two minutes after your download has finished (a result nobody downloads is removed after 30 minutes).

Troubleshooting

My PNG got much bigger as JPG or the reverse

PNG is lossless and is large for photographs; JPG is small for photographs but poor for flat graphics. Pick the format that matches the picture.

The background turned white

The target format has no transparency. Choose PNG, WebP or AVIF to keep it.

A RAW file looks flat

RAW files contain unprocessed data. Edit the converted picture in a photo editor for contrast and colour.

Available in 55 languages

The whole site - menus, buttons, guides and messages - can be switched to 55 languages, including English, Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, Assamese, Nepali, Urdu, Arabic, Spanish, French, German, Portuguese, Italian, Russian, Turkish, Japanese, Korean and Chinese. Use the language menu in the top bar; your choice is remembered, and the file formats and tools work exactly the same in every language.

Tips and good to know

JPG or PNG?

Use JPG for photos (small files). Use PNG for logos, screenshots and anything needing a transparent background.

Why use WEBP?

WEBP is usually 25-35% smaller than JPG or PNG at similar quality and is supported by all modern browsers - great for websites.

What happens to transparency?

JPG, BMP and some others can't store transparency, so transparent areas are filled with white during conversion.

Frequently asked questions

Do I lose quality?

Converting to PNG, BMP or TIFF is lossless. JPG and WEBP are lossy but use a high-quality setting.

Can I convert many images together?

Yes, any number of files in one batch, up to 200 MB in total.

Are my images private?

Yes. They are processed automatically and returned to you - we do not store them.

Convert BMP to PNG: what to know

PNG compresses a BMP without losing a single pixel. BMP is an old uncompressed Windows bitmap format. PNG is a lossless image format that supports transparency.

What changes when you convert BMP to PNG

  • Both formats are lossless, so the conversion keeps all the original data.
  • BMP has no transparency, so the result looks identical; PNG simply gives you a format that could carry transparency later.
  • Sizes are usually similar between BMP and PNG at the same visual quality.

How to convert BMP to PNG

  1. Drop your BMP file(s) onto the upload area, or click it to browse.
  2. PNG is already selected as the output format. Pick a quality level if you want a different balance of size and detail.
  3. Press Convert, then download each PNG file or all of them together as a ZIP.
