Compress Multiple Images in One Go
Stop compressing images one by one. Upload an entire batch, configure your settings once, and download everything as a single ZIP archive — with up to 90% file size reduction.
Why Bulk Compression Matters
Whether you are a web developer optimizing an entire site redesign, an e-commerce manager updating product catalogs, or a photographer delivering a client gallery, processing images one at a time is painfully slow. Each file needs uploading, configuring, compressing, and downloading individually — multiplied across dozens or hundreds of images, that adds up to hours of wasted time.
Graviton's bulk compression lets you drag and drop your entire batch at once. Every image is compressed with your chosen settings and delivered as a single ZIP file, ready to use. You can mix JPG, PNG, WebP, AVIF, and GIF files in the same batch, and each one benefits from up to 90% size reduction without visible quality loss.
Multi-File Upload
Drag and drop or select multiple images at once. Graviton accepts JPG, PNG, WebP, AVIF, and GIF files up to 50MB each, so you can upload an entire folder of assets in a single action.
Batch Processing
All images in your batch are compressed simultaneously using server-side streaming. There is no waiting for one file to finish before the next begins — the entire batch processes in parallel.
ZIP Archive Download
When your batch is complete, Graviton packages every compressed image into a single ZIP archive. One click, one download — your optimized images are ready to deploy.
Mixed Format Support
You do not need to separate files by format. Upload a mix of JPG, PNG, WebP, AVIF, and GIF images in the same batch. Graviton handles each format with the appropriate compression algorithm.
How Bulk Compression Works
Four simple steps from upload to optimized ZIP download.
Upload Multiple Files
Select or drag and drop all the images you want to compress. Mix and match formats freely — JPG, PNG, WebP, AVIF, and GIF are all supported, up to 50MB per file.
Configure Your Settings
Choose your output format, quality level, and any format-specific options. Your settings apply to all images in the batch for consistent results.
Process All at Once
Hit compress and Graviton processes every image in parallel using server-side streaming. Watch the progress as each file is optimized with up to 90% size reduction.
Download Your ZIP
All compressed images are packaged into a single ZIP archive. Download it with one click and your optimized files are ready to use immediately.
Benefits of Bulk Compression
Save time and effort with batch image processing.
Massive Time Savings
Compress dozens of images in the time it would take to process one. Batch workflows eliminate the repetitive upload-compress-download cycle.
Consistent Quality
Apply identical compression settings across your entire batch so every image meets the same quality and file size standards.
ZIP Convenience
A single ZIP download means no managing individual files. Unzip and your compressed images are organized and ready to deploy.
Mixed Format Batches
Combine JPG, PNG, WebP, AVIF, and GIF files in one batch. Graviton applies the right algorithm for each format automatically.
Batch-Wide Settings
Set your quality, output format, and other options once and they apply to every file in the batch — no per-file configuration needed.
Generous Limits
Free users get 10 compressions per day. Starter ($2/month) gets 30, and Pro ($5/month) gets 100 — enough for serious batch workflows.
Frequently Asked Questions
The number of images per batch depends on your plan. Free users can compress up to 10 images per day, Starter plan users get 30 per day, and Pro plan users get 100 per day. Each individual file can be up to 50MB in size.
There is no hard limit on the total ZIP size. The ZIP archive contains all your compressed images, which are significantly smaller than the originals. Since compression typically reduces file sizes by up to 90%, even large batches produce manageable ZIP files.
Yes. You can upload JPG, PNG, WebP, AVIF, and GIF files together in a single batch. Graviton detects each file's format and applies the appropriate compression algorithm. You can also convert all files to a single output format if you prefer.
Batch compression applies the same settings across all files for consistency and speed. If you need different settings for specific images, you can process them in separate batches or compress them individually with custom configurations.
Graviton uses server-side streaming to process images in parallel, so batch compression is significantly faster than compressing files one at a time. Processing speed depends on the number and size of your images, but most batches complete within seconds.
