Free Image Converter Online
Convert JPG, PNG, WebP, and AVIF images instantly
About this tool
Convertit's image converter helps creators, store owners, students, developers and everyday users turn one image format into another without installing editing software. Upload a JPG, PNG, WebP, AVIF, GIF or BMP image, choose the output format, set the quality when the format supports it, and download the converted file when processing is complete.
The tool is useful when a website rejects a file type, a social platform prefers a different format, a design export is too large, or you need a transparent PNG instead of a compressed JPG. It is built for quick, practical conversion rather than heavy photo editing, so the workflow stays simple: pick the file, choose the format, convert and move on.
Your files are handled as temporary processing inputs. Convertit does not ask you to create an account for image conversion, and processed files are removed automatically after the cleanup window. That makes the converter a good fit for routine work such as preparing blog images, product photos, profile pictures, thumbnails, documentation screenshots and lightweight design assets.
How to use Image Converter
- Upload the image you want to convert by dragging it into the upload area or selecting it from your device.
- Choose the output format: PNG for transparency, JPG for small photos, WebP for modern web use, AVIF for maximum compression, or GIF for simple compatibility.
- Adjust the quality value if you are converting to a lossy format such as JPG, WebP or AVIF.
- Start the conversion and wait for the progress panel to finish.
- Download the converted image and use it in your website, document, social post or design tool.
Why Convert Images?
Different platforms expect different formats. A marketplace may want JPG product photos, a website may benefit from WebP, a logo may need PNG transparency, and a modern performance workflow may use AVIF for hero images. Converting the file gives you the format that fits the destination instead of forcing the destination to accept the original export.
Image conversion also helps with performance. Large PNG screenshots and high quality JPG photos can slow down pages when they are used directly on the web. Converting to WebP or AVIF often reduces file size while keeping the image visually sharp enough for visitors. Smaller images load faster, use less bandwidth and create a smoother experience on mobile connections.
JPG vs PNG vs WebP vs AVIF
JPG is best for photographs and realistic images where small file size matters more than perfect preservation. PNG is best when you need transparency, crisp UI screenshots, icons or graphics with sharp edges. WebP is a strong default for websites because it supports small files, good visual quality and transparency in many cases. AVIF usually compresses even smaller than WebP, but some older tools and workflows may not support it as widely.
A practical rule is simple: use JPG for everyday photos, PNG for transparent or lossless graphics, WebP for most website images, and AVIF when you are optimizing aggressively for speed and your audience uses modern browsers. If you are unsure, WebP is often the safest modern web choice, while PNG is safest for transparent assets.
Frequently asked questions
Everything you need to know about this tool.
What image formats are supported?
Our image converter supports JPG, JPEG, PNG, WebP, AVIF, GIF and BMP formats. You can convert between any of these formats.
Is there a file size limit?
You can upload images up to 50MB per file. For most users this is more than enough for any image.
Are my images stored on your server?
No. All processed images are automatically deleted from our servers after 2 hours. We do not store, share or analyze your images.
Will I lose image quality during conversion?
You can choose the output quality. JPG and WebP support quality settings, while PNG is lossless. For best results, we recommend keeping quality at 85-95%.
Is the image converter really free?
Yes, our image converter is 100% free with no watermarks, no signups, and no hidden fees. We support the service through ads.
Which format should I choose for a website?
WebP is a strong default for most websites because it keeps files small while preserving good visual quality. AVIF can be even smaller, but WebP is more widely supported in older workflows.
Can I keep a transparent background?
Choose PNG or WebP if you need transparency. JPG does not support transparency and will replace transparent areas with a solid background.
What quality setting should I use?
For JPG and WebP, 80-90 is a good range for most uses. Use a higher value for portfolios and product photos, or a lower value when small file size matters most.
Can I convert images on mobile?
Yes. The converter works in modern mobile browsers, so you can upload, convert and download images from a phone or tablet.
Does conversion resize my image?
No. This tool changes the file format. Use the image resizer if you also need to change width or height.
Can I convert PNG to JPG?
Yes. Upload a PNG image, choose JPG as the output format, adjust quality if needed, and convert.
Can I convert WebP to JPG?
Yes. Upload a WebP image and choose JPG. This is useful when older apps, forms or editors do not accept WebP files.
