Why Convert to JPG?

Universal Format

JPG is supported by every device, browser, and platform — the safest choice for sharing.

Small Files

JPG compression produces compact files ideal for email, web, and social media.

Photo Quality

JPG excels at compressing photographs with minimal visible quality loss.

Adjustable Quality

Fine-tune the quality slider to find the perfect balance of size and visual fidelity.

Why JPG Remains the Universal Choice for Professional Image Delivery

Despite newer formats offering superior compression, JPG maintains its position as the default delivery format across entire industries. Real estate photography platforms like MLS require JPEG submissions. Stock photography marketplaces — Shutterstock, Adobe Stock, Getty Images — mandate JPEG for contributor uploads. E-commerce platforms including Amazon and eBay display product images as JPEG regardless of upload format. Converting to JPG ensures your images meet these universal requirements without friction.

Email marketing represents the single largest use case where JPG is not just preferred but effectively required. Outlook desktop renders images through Word's HTML engine, which does not support WebP or AVIF. Apple Mail supports WebP but many corporate email security gateways strip non-standard image formats. Campaign Monitor's 2025 rendering report found that JPEG achieves 99.7% display success across 80+ email clients tested — no other format exceeds 83%.

Print production workflows are built around JPEG and TIFF. Commercial printers, large-format signage companies, and packaging manufacturers all accept JPEG at quality 92+ with CMYK color profiles. Converting your images to JPG with an embedded sRGB or Adobe RGB profile before submitting to print vendors prevents color shifts that occur when printers auto-convert from unfamiliar formats. A well-prepared JPEG at 300 DPI delivers predictable, professional print results every time.

Social media platforms aggressively re-encode uploaded images regardless of source format. Instagram converts everything to JPEG at approximately quality 70, Facebook uses JPEG quality 71-85 depending on image dimensions, and Twitter compresses to JPEG quality 85. Uploading a carefully optimized AVIF to these platforms is counterproductive — they discard your compression work and re-encode to JPEG anyway. Starting with a quality-92 JPEG gives the platform's re-encoder the best possible source material.

Pro Tips

  • Use quality 92 for print-destined images, quality 80-85 for web

    Print reveals compression artifacts that screens hide. At 300 DPI, JPEG artifacts in sky gradients and skin tones become visible at quality 85 and below. For web delivery, quality 80-85 is the sweet spot where file size drops 40-60% compared to quality 92 with minimal perceptual difference on screen.

  • Strip EXIF metadata for web images to save 10-50 KB per file

    Camera EXIF data (GPS location, camera model, exposure settings) can add 10-50 KB to each JPEG. For web delivery, this data is unnecessary and may expose private location information. Krunkit strips EXIF during conversion while preserving the ICC color profile.

  • Convert transparent PNGs to JPG with a white background for email

    Since JPEG cannot store transparency, transparent areas become black by default in many converters. Krunkit composites transparent regions onto a clean white background before encoding, preventing the jarring black-background issue common in careless PNG-to-JPEG conversion.

Frequently Asked Questions

What image formats can I convert to JPG?

You can convert PNG, WebP, and AVIF images to JPG using our free converter.

Is JPG good for all types of images?

JPG is best for photographs and complex images. For graphics with text or sharp edges, PNG may be better.

What quality setting should I use?

Quality 80 is a great default. Use 90+ for important photos, or 60-70 for maximum compression.

Are my images uploaded anywhere?

No. All processing happens locally in your browser using WebAssembly.
