Bulk Image Compressor: Compress Images Under 100KB, 200KB, 300KB or Custom Size

Need to compress many images quickly without editing them one by one? Filego’s Bulk Image Compressor lets you compress multiple images at once, upload folders, convert to WebP, and download everything in a ZIP from a single workflow.

This tool is useful when you need images under a specific size limit for websites, e-commerce uploads, business listings, forms, portfolios, blog posts, and faster mobile performance. Image compression also supports page speed and a better on-page experience when combined with modern formats and good image SEO practices.

Why target-size image compression matters

Many users are not searching for general image optimization. They specifically need to compress images under 100KB, under 200KB, under 300KB, or to an exact custom size because upload limits and performance budgets are often strict.

That is where Filego’s size-based compression modes help. Instead of guessing the right settings manually, you can choose a target that matches your actual use case and process multiple images in one session.

Compress images under 100KB

The Compress to 100KB mode is ideal when your priority is lightweight web delivery. It works well for thumbnails, listing cards, blog images, and mobile-friendly assets where smaller file size matters most.

Best use cases include:

• Blog thumbnails
• Product listing cards
• Directory images
• Marketplace uploads
• Lightweight mobile web assets

Compress images under 200KB

The Compress to 200KB mode gives a stronger balance between file size and visible quality. It is a practical choice for product photos, article images, and standard website visuals that need to stay sharp without becoming heavy.

Best use cases include:

• Product photos
• Article images
• Landing page visuals
• Listing photos
• Portfolio previews

Compress images under 300KB

The Compress to 300KB mode is better for images that need to preserve more detail, such as large visuals, interface screenshots, banners, and richer marketing creatives. It still reduces unnecessary weight while allowing more room for quality retention.

Best use cases include:

• High-detail product images
• UI screenshots
• Marketing banners
• Presentation graphics
• Hero-supporting visuals

Compress images to custom size

Some workflows require exact control. Filego’s Custom Size option lets you define your own target when a platform, client, or internal performance standard requires a specific image limit.

Custom size is useful when:

• A CMS has a fixed upload cap
• A client asks for exact output limits
• You want tighter SEO performance control
• You are preparing images for ads, email, or app assets

Features built into Filego’s bulk image editor

Filego’s bulk image editor is designed around practical batch workflows. The page supports folder upload, ZIP export, output format selection, and bulk queue processing directly inside the editor.

Upload single files, multiple images, or folders

The editor supports adding images individually, selecting multiple images, or uploading a folder for larger batches. Folder support is especially helpful when files are organized by project, product, or client work.

Compression presets

Users can start with presets such as Maximum Compression, Best Quality, Recommended, or Custom. These presets reduce friction and help different users start with the right balance of quality and size.

Target-based compression modes

The editor supports practical compression modes built around real intent:

• Best Compression
• Compress to 100KB
• Compress to 200KB
• Compress to 300KB
• Custom Size

This is valuable because many users search by final file-size target, not just by general tool type.

Convert to WebP

The editor includes output format selection and promotes WebP as the recommended option. WebP is commonly used for web optimization because it can reduce file size while maintaining good visual quality in many scenarios.

Quality and effort controls

The tool includes a quality setting and an effort control so users can fine-tune the tradeoff between processing time, image detail, and compression efficiency. This is especially useful for product photos, screenshots, or mixed image batches.

Private by default

The interface highlights privacy as a core benefit by stating that images stay on your device during compression. That makes the tool useful for internal files, client assets, and workflows where browser-based processing matters.

Queue, progress, and savings tracking

The editor is built to show compression progress, file counts, and overall savings as part of the batch workflow. This makes it easier to evaluate results before downloading the final package.

Download everything as ZIP

After compression, users can export all outputs together as a ZIP. That is a strong usability feature for bulk processing because it simplifies asset delivery and upload into websites, stores, or CMS workflows.
