How to Convert Images Between PNG, JPG, WebP, and HEIC

Different image formats serve different purposes: JPG is ideal for photographs, PNG supports transparency, WebP offers superior compression, and HEIC is Apple's space-saving format. Converting between formats ensures compatibility across devices and platforms while optimizing file size. This guide shows you how to convert images between PNG, JPG, WebP, and HEIC formats using fixie.tools — free, no signup, and with batch processing support.

Step 1: Open the Image Format Converter

Navigate to fixie.tools/convert in your web browser. The tool works on all devices and supports conversion between JPG, PNG, WebP, and HEIC formats without requiring any software installation or account creation.

Step 2: Upload Your Images

Click the upload area or drag and drop your image files. You can upload multiple images at once for batch conversion, which is useful when converting an entire photo library or set of assets. Supported input formats include JPG, PNG, WebP, HEIC, BMP, and TIFF. Each file can be up to 25MB.

Step 3: Select Output Format

Choose your desired output format from the dropdown menu. JPG is best for photographs and images with many colors (but doesn't support transparency). PNG is ideal for graphics, logos, and screenshots that need transparency or lossless quality. WebP offers better compression than JPG with similar quality, making it great for web use. HEIC is Apple's format with excellent compression but limited browser support.

Step 4: Configure Conversion Settings

Adjust optional settings based on your needs. For JPG output, set the quality level (75-90 recommended for web use). For PNG output, choose between smaller file sizes or faster conversion. For WebP, select lossy (smaller files) or lossless (perfect quality) compression. The tool displays estimated output file sizes for each option.

Step 5: Convert and Download

Click the convert button to process your images. Conversion typically takes 2-5 seconds per image. Once complete, download individual converted images or use the 'Download All' button to get a ZIP file with all converted images. Original files are automatically deleted from our servers after 24 hours.

Frequently Asked Questions

When should I use JPG vs PNG vs WebP?
Use JPG for photographs and images with gradients where small quality loss is acceptable. Use PNG for graphics, logos, screenshots, or any image requiring transparency. Use WebP when you need smaller file sizes than JPG with similar quality, especially for web use. Modern browsers support WebP, but for maximum compatibility, stick with JPG or PNG.
Can I convert HEIC images from iPhone to JPG?
Yes, Fixie supports converting HEIC (Apple's High Efficiency Image Format) to JPG, PNG, or WebP. This is useful when sharing iPhone photos with Android users or uploading to websites that don't support HEIC. The conversion maintains image quality while improving compatibility.
Does converting from PNG to JPG lose quality?
PNG uses lossless compression, while JPG uses lossy compression, so some quality loss is inevitable when converting from PNG to JPG. However, with high quality settings (85-95), the difference is usually imperceptible. The main advantage is significantly smaller file sizes. Note that JPG doesn't support transparency, so transparent areas will become solid color (usually white).
Is the image converter free with no limits?
Yes, Fixie's Image Format Converter is completely free with no file limits, no signup requirements, and no watermarks. Unlike tools like CloudConvert that limit free users to 25 conversions per day, Fixie has no such restrictions.
Can I convert images without uploading them?
Currently, Fixie's converter requires uploading files to our servers for processing. Your files are automatically deleted after 24 hours. For maximum privacy when converting sensitive images, consider using desktop software that processes files locally without uploading.
