What is JPG?

JPG (or JPEG) is the most widely used image format in the world. Developed by the Joint Photographic Experts Group in 1992, it uses lossy compression to dramatically reduce file sizes while maintaining acceptable visual quality for photographs.

A 10MB raw photo typically compresses to 500KB-2MB as a JPG with no visible difference to most viewers. This efficiency made JPG the standard for digital cameras, web images, social media, and email attachments.

JPG works everywhere—every device, browser, app, and operating system supports it. When you need an image to just work, JPG is the safe choice.

Why Convert to JPG?

JPG solves common image problems:

Universal compatibility – JPG opens on every device and platform without special software
Smaller file sizes – Photos compress 10-20x smaller than raw or lossless formats
Faster uploads – Smaller files upload quickly to social media, email, and websites
HEIC compatibility – iPhone photos (HEIC) need conversion for Windows and many apps
Web optimization – JPG remains the best balance of quality and size for most web images
Email attachments – Stay under attachment size limits with compressed JPG files

When in doubt about format compatibility, convert to JPG.

Convert Other Formats to JPG

Any image format can become a JPG:

PNG to JPG

The most common conversion. PNG files are often 3-10x larger than JPG for the same image. Convert when you don't need transparency and want smaller files for sharing or web use.

HEIC to JPG

Essential for iPhone users. HEIC is Apple's default photo format but isn't supported on Windows or many websites. Convert to JPG for universal sharing.

WebP to JPG

WebP is great for websites but less compatible elsewhere. Convert to JPG when sharing images via email or with people who might have compatibility issues.

RAW to JPG

Camera RAW files (CR2, NEF, ARW) are huge and require special software. Convert to JPG for sharing and casual viewing while keeping RAW originals for editing.

TIFF to JPG

TIFF files from scanners or professional workflows are too large for sharing. Convert to JPG for email, web, or when recipients don't need the full quality.

BMP to JPG

BMP screenshots are massive. Convert to JPG to reduce file size by 90% or more for practical use.

Convert JPG to Other Formats

Sometimes you need a different format:

JPG to PNG

When you need to add transparency, edit the image repeatedly, or preserve exact quality. Note that converting JPG to PNG doesn't improve quality—the JPG compression is already permanent.

JPG to PDF

Combine photos into a document format for printing, archiving, or sharing multiple images as one file. Great for creating photo albums or documentation.

JPG to WebP

WebP is 25-35% smaller than JPG at equivalent quality. Convert for website optimization when you control the viewing environment.

JPG to HEIC

Rarely needed, but HEIC can be even smaller than JPG for Apple device storage. Most users go the opposite direction.

JPG Limitations

No transparency – Transparent areas become white (or black)
Lossy compression – Re-saving degrades quality over time
Text/line art – Sharp edges get blurry artifacts
Color limitations – No HDR or wide color gamut support

How to Convert to JPG

Upload your image – Any format: PNG, HEIC, WebP, TIFF, BMP, RAW, or others. Batch upload multiple files for bulk conversion.
Adjust quality (optional) – Higher quality means larger files. 80-90% is usually indistinguishable from 100% at a fraction of the file size.
Download your JPG – Get universally compatible images ready for any use.

Conversion is instant and happens in your browser—your images stay private.

JPG Quality Settings Explained

Understanding the quality slider:

90-100%: Minimal compression, large files. Only needed for archival or professional print.
80-90%: Sweet spot. Files are 50-70% smaller with no visible difference. Recommended for most uses.
60-80%: More compression artifacts visible on close inspection. Good for thumbnails and web previews.
Below 60%: Noticeable quality loss. Only use for extreme file size reduction.

For most sharing purposes, 85% quality is ideal—visually identical to 100% at less than half the file size.

When NOT to Use JPG

Despite being universal, JPG isn't always the right choice:

Images with transparency – Use PNG or WebP instead
Text and screenshots – PNG preserves sharp edges better
Graphics and logos – PNG or SVG for crisp lines
Images you'll edit repeatedly – Use PNG to avoid cumulative quality loss
Archival masters – Keep originals in lossless formats

JPG excels at photographs but struggles with non-photographic content.

Expert Tips for JPG

Pro Tip

For web images, use progressive JPG encoding—images load as gradually sharpening previews instead of top-to-bottom. This improves perceived load time, especially on slow connections.

Common Mistake

Repeatedly saving a JPG after editing. Each save recompresses and degrades quality. Edit in PNG or your editor's native format, then export to JPG only as the final step.

Best For

Photographs, complex images with gradients, and any situation requiring universal compatibility. JPG is the 'it just works' format for photos across all devices and platforms.

Not Recommended

Screenshots, text, logos, line art, or images requiring transparency. These need PNG's lossless compression and sharp edge preservation. Also avoid for images you'll edit repeatedly.

overview

Files stored in this format are small in size that is why they can be uploaded and downloaded with ease. It takes less time over the internet to upload and download due to smaller size which results in saving of bandwidth. This extension is compressed using a lossy algorithm that is why there can be a reduction in the quality of the photograph. It has the ability to compress the file to one-tenth of its original size. It is widely used in emails and also when images are to be posted on websites. Digital Cameras and other photographic image capture devices widely use this JPG format. The paintings and photos of realistic scenes that have smooth variations of colour can be best illustrated by this format.

technical description

A technique used in JPEG format to compress files is lossy compression which is based on DCT (Discrete Cosine Transform) as it is the most practical Mathematical operation. The DCT actually converts each frame of the video from the spatial domain to a frequency/transform domain. It discards the information of high frequency that has sharp transitions in intensity as well as in colour hue. Furthermore, this standard defines a codec which tells how an image can be encoded into a stream of bytes and decoded back into an image. The files can be compressed in the ratio of 100:1 but that would result in the poor quality of an image. Therefore, to retain the quality of a photo, a file should be compressed till 20:1 ratio not more than that.

Frequently asked questions

JPG (JPEG) is the most common image format, developed in 1992 for efficient photo storage. It uses lossy compression to reduce file sizes dramatically while maintaining good visual quality, making it perfect for photos and web use.

Yes—they're identical. Both extensions refer to the same format. 'JPG' became common because older Windows versions only allowed 3-letter extensions. Use either; all software treats them the same.

Upload your HEIC file (iPhone's default photo format) and select JPG as output. The converted JPG works everywhere—Windows, Android, social media, and email—unlike HEIC which has limited compatibility.

JPG uses lossy compression, so there's some quality loss. However, at 85-90% quality settings, the difference is invisible to most viewers. The massive file size reduction usually outweighs the imperceptible quality trade-off.

Try a lower quality setting (80-85% instead of 100%) or resize the image dimensions. A 4000x3000 pixel photo is much larger than necessary for web or email—resizing to 1920x1440 significantly reduces file size.

Converting JPG to PNG doesn't improve quality—the JPG compression already permanently removed data. The PNG will look the same but be larger. Keep originals if you need lossless quality.

85% for most uses—visually identical to 100% at roughly half the file size. Use 90-95% for professional or print work. Below 80% shows noticeable compression artifacts.

JPG doesn't support transparency. Transparent areas in your PNG or GIF source become solid (usually white). If you need to preserve transparency, use PNG or WebP instead.

Yes. Upload multiple files and batch convert them all to JPG simultaneously. All converted images download together, saving time when processing many files.

WebP is 25-35% smaller than JPG at the same quality and supports transparency. However, JPG has universal compatibility while WebP still has some edge cases. For websites, WebP is better; for sharing, JPG is safer.
