Working with images often means dealing with incompatible formats — a client sends a PNG when you need a JPG, a screenshot tool saves as BMP when you need WebP, or a designer delivers TIFF files that won't display on the web. Our free online image format converter solves this problem instantly. Convert between PNG, JPG, WebP, GIF, BMP, ICO, and AVIF with a single click, right in your browser.

What Is Image Format Conversion?
Image format conversion is the process of re-encoding an image file from one format to another. Different image formats use different compression algorithms and feature sets. When you convert a PNG to a JPG, for example, the converter reads the pixel data from the PNG file and re-encodes it using JPEG compression.
This matters because different use cases demand different formats. Web pages benefit from WebP's superior compression, print workflows require lossless PNG or TIFF, and favicons need ICO files. Having a fast, reliable converter means you never have to worry about format compatibility again.
Understanding Common Image Formats
Before converting, it helps to understand what each format does best:
| Format | Compression | Transparency | Best For |
|---|
| PNG | Lossless | Yes (alpha channel) | Screenshots, logos, graphics with text |
| JPG/JPEG | Lossy | No | Photographs, complex images with gradients |
| WebP | Both lossy & lossless | Yes | Web images (25-35% smaller than PNG/JPG) |
| GIF | Lossless (256 colors) | Yes (binary only) | Simple animations, pixel art |
| BMP | Uncompressed | No | Raw image data, legacy systems |
| ICO | Varies | Yes | Website favicons, app icons |
| AVIF | Both lossy & lossless | Yes | Next-gen web images (50% smaller than JPG) |
| TIFF | Both | Yes | Print production, archival scans |
How to Use the Image Format Converter
- Upload your image — Drag and drop or click to select a file. We support all major image formats including PNG, JPG, WebP, GIF, BMP, TIFF, SVG, and AVIF.
- Select the target format — Choose from the format dropdown: PNG, JPG, WebP, GIF, BMP, ICO, or AVIF.
- Adjust quality settings — For lossy formats (JPG, WebP), use the quality slider (0–100). Higher quality means larger files; lower quality means smaller files with some visual loss.
- Download the converted file — Click download to save your image. You can also batch convert multiple files at once.
Like all RiseTop tools, the converter runs entirely in your browser. No files are uploaded to any server, and there's no limit on the number of conversions you can perform.
Step-by-Step Conversion Examples
Example 1: Convert PNG to JPG for Smaller File Size
PNG files are often 3–5× larger than equivalent JPG files because PNG uses lossless compression. If you have a photograph saved as PNG, converting to JPG can dramatically reduce the file size:
- Upload your PNG photo to the format converter.
- Select
JPG as the output format.
- Set quality to
85 — this provides an excellent balance of quality and file size reduction.
- Download the result. A typical 5 MB PNG photograph will become roughly 500 KB–1 MB as a JPG at quality 85.
Note: Converting PNG to JPG removes transparency. If your image has a transparent background, it will be replaced with white (or another background color you choose).
Example 2: Convert JPG to WebP for Web Performance
WebP is the modern web standard, supported by all major browsers since 2020. It provides 25–35% smaller files than JPG at equivalent quality:
- Upload your JPG image.
- Select
WebP as the output format.
- Set quality to
80 (WebP's quality scale is different from JPG — 80 in WebP looks equivalent to 85–90 in JPG).
- Download the WebP file and use it on your website for faster page loads.
Example 3: Create a Favicon from a PNG
Every website needs a favicon — the small icon in the browser tab. Converting a logo PNG to ICO format is straightforward:
- Start with a square PNG (ideally 256×256 or larger). If your image isn't square, use our image cropper first.
- Upload to the format converter and select
ICO as the output.
- Download and place it in your website's root directory as
favicon.ico.
Common Use Cases
Web Development & Optimization
Converting images to WebP or AVIF can reduce page weight by 30–50%, directly improving Core Web Vitals scores. Many CDN and hosting platforms now auto-convert images, but having a manual converter ensures you control quality and can optimize images before deployment.
Email Marketing
Email clients have inconsistent image format support. While most modern clients handle PNG and JPG well, some older clients struggle with WebP or AVIF. Converting all email images to JPG ensures maximum compatibility across email clients.
Social Media Uploads
Each social platform has preferred formats and file size limits. Instagram compresses JPGs heavily but handles PNGs differently. Twitter converts all uploads to JPG. Converting your images beforehand with the right quality settings can sometimes produce better results than letting the platform do it.
Print & Publishing
Print workflows typically require TIFF or high-quality PNG files. Converting from compressed formats like JPG to lossless PNG before sending files to print can prevent banding artifacts and color shifts.
Lossy vs. Lossless Conversion: What You Need to Know
The most important concept in format conversion is the difference between lossy and lossless compression:
- Lossless conversion (e.g., PNG → TIFF) preserves every pixel exactly. You can convert back and forth without any quality loss.
- Lossy conversion (e.g., PNG → JPG) discards some image data to achieve smaller file sizes. This data is gone permanently — you can't recover it by converting back.
Rule of thumb: always keep your original files. Convert copies for specific use cases, and keep the originals in a lossless format as your master copies.
Frequently Asked Questions
Will converting PNG to JPG reduce quality?
JPG uses lossy compression, so there is always some quality loss. However, at quality settings of 85 or above, the difference is virtually invisible to the human eye in photographs. For images with sharp text, fine lines, or solid colors (like screenshots or logos), the quality loss is more noticeable — stick with PNG for those.
Can I convert multiple images at once?
Yes, our converter supports batch conversion. Upload multiple files at once, select your target format and quality settings, and download all converted files together or individually.
What happens to transparency when converting to JPG?
JPG doesn't support transparency. When converting a PNG with a transparent background to JPG, the transparent areas will be filled with a solid color (white by default). If you need to preserve transparency, convert to WebP or PNG instead.
Is WebP supported by all browsers?
WebP is now supported by all major browsers including Chrome, Firefox, Safari (since version 14), Edge, and Opera. As of 2026, global WebP support exceeds 97%. For the remaining edge cases, you can serve JPG as a fallback.
Is there a file size limit?
There's no strict file size limit, but very large images (over 100 MB) may be slower to process since everything runs in your browser's memory. For most use cases, files up to 50 MB convert instantly.
