What's the difference between PNG and JPEG?

PNG uses lossless compression, supports transparency, and produces larger files — perfect for logos, screenshots, and any graphic with crisp text. JPEG uses lossy compression that trades some quality for much smaller files and ignores transparency entirely, which makes it the right pick for photographs. Match the format to the content rather than picking one universally.

When should I use WebP?

WebP compresses 25 to 35 percent more efficiently than PNG or JPEG at comparable quality, and every modern browser supports it. Use it for web images where bandwidth genuinely matters; you only need a PNG or JPEG fallback if you're still serving very old browsers, which is rare in 2024.

Will conversion reduce image quality?

It depends on the direction. Anything that produces a JPEG or lossy WebP loses a small amount of quality, while lossless paths like PNG to lossless WebP or BMP to TIFF preserve quality exactly. Most converters let you choose a quality level for lossy formats, where higher numbers mean larger files and fewer artifacts.

How does it handle transparency?

Transparency survives or dies based on the target format. Going from PNG to JPEG flattens transparent areas to a solid background color. PNG to WebP keeps transparency intact because WebP supports it natively, and PNG to PNG obviously preserves it. Always check the result before assuming transparency made it through.

Are large images supported?

Mostly, with limits. Modern browsers handle images up to about 50MB without trouble, and beyond 100MB things start getting slow or unstable. For genuinely massive batch processing, server-side tools like ImageMagick or Sharp are far more efficient than asking a browser tab to chew through dozens of huge files.

Does converting affect EXIF data?

Some converters preserve EXIF metadata while others strip it. Stripping is the privacy-friendly default because EXIF often contains GPS coordinates, timestamps, and device fingerprints you don't want to leak when sharing photos publicly. For archival and professional photography, preserving the metadata is usually the desired outcome instead.

Is the image sent to a server?

No. Conversion runs in the browser through the Canvas API, which is exactly what you want for confidential photos, unreleased brand assets, or any image you'd rather not upload.

About Image Format Converter

Convert images between different formats: PNG, JPEG, WebP, GIF, and BMP. Adjust quality for lossy formats. All processing happens in your browser.

How to Use Image Format Converter

Upload source image

Drag the file into the workspace or click to browse. The converter accepts PNG, JPEG, WebP, GIF, BMP, and most other common image formats your browser can decode.

Choose target format

Pick where the image is going. PNG keeps everything lossless and supports transparency, JPEG produces smaller files for photos, and WebP is the modern web default that often beats both on size.

Adjust quality for lossy formats

For JPEG and lossy WebP exports, the quality slider runs from 1 to 100. Higher values mean larger files but cleaner results, and a default around 85 to 90 percent strikes the right balance for almost any web use case.

Download converted image

Click Download to save the converted file. From there, drop it into your project, upload it to a CMS, or share it however the destination expects.

When to Use Image Format Converter

Web optimization

Switching PNGs to WebP typically shaves around 30 percent off file size at comparable quality, and JPEGs converted to WebP usually shrink further still. Every modern browser handles WebP, so the savings translate directly into faster page loads, lower bandwidth bills, and better Core Web Vitals scores.

Format compatibility

Different platforms have stubborn preferences. WhatsApp tends to favor JPEG, Slack accepts almost anything, and iOS uses HEIC by default. Converting an image to the format your destination expects is the simplest way to avoid silent quality loss or upload failures, especially when sharing with non-technical recipients.

Reducing file size for emails and uploads

Email attachments and many web upload forms cap at a few megabytes. Converting a photo from PNG to JPEG often cuts the size by 90 percent or more without any visible quality difference, which is enough to slip under most limits without the recipient noticing the change.

Format-specific use cases

PNG fits logos and any graphic with text or transparency because it's lossless. JPEG suits photos, where smaller sizes matter and transparency doesn't. GIF still owns simple animations on legacy clients. WebP is the modern web default, and AVIF pushes compression even further for cutting-edge sites willing to deal with slightly newer support.

Image Format Converter Examples

PNG to JPEG for smaller files

Input

Logo.png (500 KB)

Output

Logo.jpg around 50 KB, roughly a 90 percent reduction.

PNG is larger than JPEG for any image that doesn't actually need lossless quality, especially photographs. Converting a PNG with no real need for transparency drops the file size dramatically, and a quality setting around 85 to 90 percent strikes the right balance between size and visible artifacts.

JPEG to WebP for the modern web

Input

Photo.jpg (300 KB)

Output

Photo.webp at about 210 KB, around 30 percent smaller.

WebP compresses more efficiently than JPEG at the same perceived quality. Chrome, Firefox, and Safari all support it natively, so the savings translate directly into less bandwidth, faster pages, and better Core Web Vitals scores for your readers.

GIF to WebP for animations

Input

Animated.gif (1 MB)

Output

Animated.webp around 300 KB.

Animated GIFs are notoriously bloated because GIF compression is from another era. Animated WebP cuts the file size by two-thirds or more while keeping the animation smooth, which matters a lot on pages where multiple loops are competing for the same bandwidth.

Tips & Best Practices for Image Format Converter

1.Pick the format around the content. Photos belong in JPEG or WebP, logos and graphics with text belong in PNG or lossless WebP, and animations either stay as GIF for maximum compatibility or move to WebP for far better compression.
2.WebP is safe to use as your default in 2024 — global support sits above 95 percent. Only bother with PNG or JPEG fallbacks if you genuinely need to support legacy Internet Explorer or some obscure embedded browser.
3.Lossy formats trade quality for size. Around 85 to 90 percent quality is essentially invisible to most viewers, but dropping below 70 percent starts producing visible block artifacts that are hard to scrub out later.
4.Converting PNG to JPEG silently flattens transparency to a solid background color. If transparency matters, route through WebP or stay on PNG instead of accepting an unexpected white halo.
5.For large batches, ImageMagick or cwebp on the command line is much faster than running each file through a browser. Browser tools shine for the occasional one-off; scripts shine when the work measures in dozens of files or more.
6.Strip EXIF before publishing photos. Cameras embed GPS coordinates, timestamps, and device fingerprints in every shot, and most converters offer an option to drop those fields during conversion.

Frequently Asked Questions

The common ones cover most needs. PNG is lossless and supports transparency, JPEG (or JPG) is lossy with smaller files but no transparency, WebP is the modern option with both lossless and lossy modes, GIF still owns simple animation, and BMP shows up as uncompressed exports from older tools. Beyond those, TIFF appears in archival workflows and AVIF pushes compression further than WebP, though browser-based conversion of those rarer formats can be patchy.
