Why Convert Images to JPG?
- Universal compatibility — JPG is supported by every device, browser, image viewer, social media platform, and email client
- Smaller file sizes — A 10 MB PNG can become a 500 KB JPG with minimal visible quality loss
- Wide upload acceptance — Many online forms, job applications, and e-commerce platforms specifically require JPG
JPG vs JPEG: What's the Difference?
Nothing. JPG and JPEG are the exact same format. The only reason both names exist is historical — early Windows systems limited file extensions to 3 characters (.jpg), while Mac and Linux used the full .jpeg extension. They are 100% identical.
Converting Specific Formats to JPG
PNG to JPG
The most common conversion. Converting PNG to JPG typically reduces file size by 60-80%. Use this when the image is a photograph and you don't need transparency.
HEIC to JPG
iPhone cameras save photos as HEIC by default — not universally supported on Windows and many websites. Read our full HEIC to JPG guide for step-by-step instructions and tips on changing your iPhone's default format.
WebP to JPG
WebP is Google's web format — great for websites, but not ideal for sharing. See our detailed WebP to JPG guide for solutions to the common "why are my images saving as WebP?" problem.
AVIF to JPG
AVIF is the newest image format, offering superior compression. But browser and software support is still catching up. Converting to JPG gives you maximum compatibility.
TIFF to JPG
TIFF files from scanners and professional cameras can be enormous (50-100+ MB). Converting to JPG makes these files practical to share and upload.
PSD to JPG
Have a Photoshop file you need to share quickly? ImageConvert.to can convert PSD directly to JPG without needing Photoshop installed.
JPG Quality Settings: Finding the Sweet Spot
| Quality | File Size | Best For |
|---|---|---|
| 95-100% | Large | Professional photography, print preparation |
| 85-90% | Medium | General purpose — photos look great, files are manageable |
| 70-80% | Small | Web thumbnails, quick sharing, email attachments |
| 50-65% | Very small | Previews, placeholders, when file size is critical |
Our recommendation: Start at 85%. This is ImageConvert.to's default because it produces files that are dramatically smaller than the original with quality differences invisible to the naked eye.
Batch Convert Images to JPG
- Select all your images at once (drag and drop or use the file picker)
- Choose JPG as the output format
- Set your quality level
- Click "Convert all"
- Download each converted file
Everything processes locally in your browser using the Canvas API — no upload time, no server queue, no daily limits.
When NOT to Use JPG
Consider converting to PNG instead if you need:
- Transparency — JPG has no alpha channel. Use PNG, WebP, or AVIF
- Text-heavy images — JPG compression creates artifacts around sharp edges and text
- Images you'll edit repeatedly — Each JPG save degrades quality slightly
- Pixel art or simple graphics — PNG compresses these more efficiently
For the best overall image conversion experience, ImageConvert.to supports all these formats.

Is there a difference between JPG and JPEG?
No. JPG and JPEG are the same format. The .jpg extension exists because early Windows limited extensions to 3 characters. Both produce identical files.
Does converting to JPG reduce quality?
Yes, JPG uses lossy compression, so some quality is lost. However, at settings of 85% or higher, the difference is virtually invisible. The file size reduction (often 60-90%) usually far outweighs the imperceptible quality loss.
