Convert images online — free, fast and private
Convert images between JPG, PNG, WEBP, AVIF, GIF, TIFF, ICO, BMP and HEIC. Free, with no software to install and no account to create.
Every photo, screenshot and graphic you use online exists in a specific file format, and that format decides how the image looks, how large the file is, and where it can be used at all. A PNG that works perfectly as a website logo will slow a blog post down. A HEIC photo from an iPhone will not open on most Windows or Android devices. A TIFF is excellent for print and useless over email.
This tool converts between every major format, in batches, in a single request — your file is re-encoded in memory and handed straight back, never written to disk and never stored. The rest of this page covers how it works, which format to choose for which job, what happens to quality along the way, and the questions people ask most often.
How it works
Three steps, start to finish
- 1
Upload your files
Drag and drop up to 30 images at once, or select them manually. Each file can be up to 50 MB. You can also paste an image straight from your clipboard with Ctrl+V.
- 2
Choose your output format
Pick JPG, PNG, WEBP, AVIF, GIF, TIFF, ICO or BMP. HEIC, BMP and ICO are accepted as source formats, so an iPhone photo can go straight to JPG.

Download the results
Convert one image or all 30 in a single run, then download them one by one or grab the whole batch as a ZIP.
Why convert
What format conversion actually solves
The right format depends entirely on where the image is going and what it needs to do there. These are the problems it fixes.
Compatibility
HEIC photos from iPhones do not open natively in many Windows apps, older Android devices, or most browsers. Converting to JPG or PNG fixes it instantly.
File size and page speed
PNG and BMP are often far larger than a photograph needs. WEBP or AVIF can shrink the file substantially at comparable quality, which helps load time and Core Web Vitals.
Transparency support
JPG cannot store a transparent background. A transparent logo or graphic has to be PNG, WEBP, GIF or ICO.
Platform requirements
Plenty of forms, marketplaces and content management systems accept only specific formats — usually JPG or PNG. Converting makes sure the file is accepted.
Print vs. screen
TIFF is the standard in professional printing and archiving. It is not meant for the web, and a web image is rarely ready for print.
Icons and favicons
Website favicons and Windows application icons need the ICO format, at specific pixel dimensions.
Animation
GIF remains the most universally supported format for a simple looping animation, even where newer formats would be smaller.
Supported formats
Every format, and what it is for
JPG, PNG, WEBP, AVIF, GIF, TIFF, ICO and BMP are available as output formats. HEIC and HEIF are accepted as sources, so an iPhone photo converts in one step.
JPG (JPEG)
Photos, everywhereThe most widely used photo format on the web. Lossy compression discards some image data to cut file size, which suits photographs with lots of colour detail. No transparency support.
PNG
Logos and screenshotsLossless, so no image data is discarded, with full alpha transparency. Best for logos, screenshots, text and anything needing sharp edges. Larger than JPG for photographs.
WEBP
The web defaultA modern Google format supporting both lossy and lossless compression, plus transparency and animation. Usually smaller than JPG or PNG at comparable visual quality.
AVIF
Smallest filesBased on the AV1 video codec, with some of the best compression efficiency available — often smaller than WEBP at the same quality. Supports transparency and HDR colour.
HEIC
Source format onlyApple's default photo format since iOS 11, using high-efficiency compression to keep files small. Not supported natively on most non-Apple devices, which is why HEIC to JPG is one of the most common conversions there is.
GIF
Simple animationAn older format capped at 256 colours, best known for short looping clips. That limited palette makes it a poor fit for photographs.
TIFF
Print and archivingUncompressed or losslessly compressed, used heavily in professional photography, scanning and print workflows. Produces large files and is not intended for the web.
ICO
Favicons and app iconsThe format behind website favicons and Windows application icons. Typically packs several small sizes — 16x16, 32x32, 48x48 — inside a single file.
BMP
Legacy WindowsAn uncompressed Windows bitmap. Very large relative to the quality it delivers, and largely superseded, but still required by some legacy software.

Why this one
What you get
Files are never stored
Your image is held in memory only for as long as the conversion takes. It is never written to disk, never saved to a database, and discarded the moment the converted file is handed back.
Batch conversion
Convert up to 30 files in one run instead of repeating yourself, and download the whole set as a single ZIP.
Generous size limit
Each file can be up to 50 MB — enough for high-resolution photographs, scans and large graphics.
Real encoding, not a rename
Conversion runs through libvips, the same image pipeline used in production by large sites. Changing a file extension by hand does not change the format; this does.
Nothing to install
Works in the browser on desktop and mobile. No app, no plugin, no extension.
Free, with no watermark
No account, no subscription, no trial, and nothing stamped across your image.
No queue
Conversion starts as soon as the upload lands. There is no waiting room and no priority tier that skips it.
Privacy & security
What happens to your file
Your image is sent over an encrypted HTTPS connection, decoded and re-encoded in memory, and returned in the same request. It is never written to disk, never saved to a database, and never queued anywhere for later processing. Once the converted file has been handed back, nothing about it remains.
That matters most for the images people are least comfortable passing around — scanned documents, ID photos, medical paperwork, unreleased client work. No account is required, so a conversion is not attached to an identity either. If you are signed in, the only thing recorded is metadata about the conversion — filename, formats and sizes — for your own history, which you can clear from your dashboard at any time.

Before you convert
Common conversion questions
Does converting an image reduce its quality?
It depends on the formats involved. Converting between two lossless formats, such as PNG to TIFF, preserves quality exactly. Converting to a lossy format like JPG discards some data, though at high quality settings the difference is usually invisible. Converting a lossy image to a lossless one does not recover quality already lost in the original compression — it only stops further loss.
Will the image dimensions change?
No. Format conversion changes how the file is encoded, not its pixel dimensions. Resizing is a separate operation, and there is a dedicated resize tool for it.
Why is my converted file larger than the original?
This happens when you convert from a highly compressed format such as AVIF or HEIC to an uncompressed or less efficient one such as BMP or TIFF, because those formats store far more raw data. It can also happen going from JPG to PNG, since PNG is lossless.
Does this work on mobile browsers?
Yes, on current versions of Chrome, Safari, Firefox and Edge on both desktop and mobile. You can pick images straight from your camera roll on iOS and Android.
Why won't my HEIC photo open on my computer?
HEIC has been Apple's default photo format since iOS 11. Many non-Apple operating systems and older applications do not support it natively. Converting to JPG or PNG resolves it.
FAQ
Frequently asked questions
What is the best image format to convert to for websites?
WEBP is generally the best balance of file size and quality for most sites today. AVIF produces even smaller files where browser support allows, and every current major browser supports it.
Is this image converter really free?
Yes. There is no cost, no account requirement and no watermark. The only limits are 30 files per batch and 50 MB per file, both of which exist to keep the server responsive rather than to sell you an upgrade.
Are my images stored on your server?
No. The image is uploaded over HTTPS, re-encoded in memory and returned in the same request. It is never written to disk, never saved to a database, and nothing is retained once the response is sent.
What's the difference between PNG and JPG?
PNG uses lossless compression and supports transparency, which makes it better for graphics, logos and text. JPG uses lossy compression and produces smaller files, which makes it better for photographs where a small quality loss is not visible.
Can I convert HEIC photos from my iPhone?
Yes. HEIC and HEIF files can be converted to JPG, PNG, WEBP, AVIF or any other supported output format. There is also a dedicated HEIC to JPG tool if that is all you need.
What is the maximum file size, and how many images at once?
Each file can be up to 50 MB, and you can convert up to 30 files in a single batch.
Does converting to AVIF work in all browsers?
AVIF is supported in current versions of Chrome, Firefox, Edge and Safari. Very old browsers may not display an AVIF image, but the file itself still converts correctly and will open in any modern viewer.
Can I convert an image to use as a favicon?
Yes. Convert your image to ICO. Starting from a square image gives the cleanest result, since a non-square source has to be fitted into a square icon.
