When to use

Converting a large collection of high-resolution photos into a web-optimized format like WebP or AVIF.
Standardizing a mix of file types, such as BMP or TIFF, into a uniform JPEG or PNG format for compatibility.
Reducing the file size of multiple images for faster website loading or email attachments without sacrificing visual quality.

1Upload up to 100 image files from your device.
2Select your desired target format and adjust quality, compression, and metadata settings.
3Click the convert button to process your files in bulk.
4Download your transformed images as a single archive or individual files.

Use cases

Web Developers: Converting raw assets to modern, lightweight formats like WebP for improved page performance.
Photographers: Batch-exporting edited images to JPEG for client delivery while preserving essential EXIF data.
Content Creators: Standardizing screenshots and graphics into a consistent format for social media or blog posts.

Examples

1. Optimizing Website Assets

Web Developer

Background

A developer has 50 high-resolution PNG images that are slowing down a website's load time.

Problem

The images need to be converted to WebP format with high compression to improve site speed.

How to use

Upload the PNG files, select 'WebP' as the target format, set quality to 75, and enable 'Optimize for Size'.

targetFormat: webp, quality: 75, optimize: true

Outcome

All 50 images are converted to WebP, significantly reducing total page weight while maintaining visual clarity.

2. Standardizing Client Deliverables

Graphic Designer

Background

A designer needs to send a set of 20 images to a client who specifically requires JPEG files.

Problem

The source files are a mix of TIFF and BMP formats, which the client cannot open.

How to use

Upload all source files, select 'JPEG' as the target format, and ensure 'Keep Original File Names' is checked.
