Bulk Image Compressor — Shrink File Sizes, Not Quality
Compress up to 50 images at once without visible quality loss. Reduce file sizes by up to 80%, convert to WebP or AVIF, and accelerate your website's load time. graficai's bulk image compressor analyzes each image individually to find the optimal size-to-quality ratio — all in a single batch.

Bloated images are silently killing your page speed and SEO
The average webpage today is 2.3MB — and images account for over 60% of that. Every unoptimized product photo, hero banner, and blog graphic adds milliseconds to your load time. Google's Core Web Vitals measure this precisely: a Largest Contentful Paint (LCP) above 2.5 seconds flags your page as 'needs improvement.' Worse, 53% of mobile visitors abandon pages that take over 3 seconds. Your images are costing you rankings, traffic, and revenue — one uncompressed file at a time.
See your potential speed gainsOne image compressor for JPEGs, another for PNGs — why?
Most compression tools specialize: one handles JPEGs well but mangles PNG transparency. Another optimizes PNGs but can't touch WebP. Your workflow becomes a fragmented mess of upload-download-upload across three different services. graficai's bulk compressor handles JPG, PNG, and WebP in a single batch, applying content-aware optimization to each file individually. JPEG gets DCT optimization. PNG gets lossless palette reduction. WebP gets perceptual encoding tuned for the image's actual content.

Compressing one image at a time doesn't scale past page one
You optimized your homepage hero image. Great. What about the 47 product photos on your category page? The 12 blog post headers from last month? The 200 supplier images waiting in your upload queue? Individual compression is a treadmill — you fix one page while three others slow down. Bulk compression solves this systemically: process every image on your site in one batch, enforce consistent optimization standards, and make page speed a solved problem rather than an ongoing firefight.
Compress your entire library at onceHow to compress multiple images in 3 steps
Upload your image batch
Drag and drop up to 50 images — JPG, PNG, WebP, or mixed. Upload from device or your graficai library. No file size limits on uploads.
Choose your compression settings
Select lossy (smallest files, imperceptible quality change) or lossless (pixel-perfect, modest savings). Optionally convert to WebP or AVIF for even greater compression.
Download optimized images
Review the compression results with original-vs-optimized size comparisons. Download individual files or grab everything as a ZIP. Your site just got faster.
Why compress images in bulk with graficai
Up to 80% size reduction
Typical compression achieves 40-80% file size savings without visible quality loss. The average product photo shrinks from 800KB to under 200KB.
Perceptual optimization
Our engine analyzes each image's content, preserving detail in focal areas while compressing backgrounds more aggressively. Smarter than uniform compression.
WebP & AVIF conversion
Compress and convert to next-gen formats simultaneously. WebP saves 25-35% vs JPEG; AVIF saves 50%+. Both support transparency.
Lossy & lossless modes
Choose lossy for maximum web savings or lossless for archival and print. Pixel-perfect preservation when you need it, maximum compression when you don't.
Direct SEO impact
Faster images mean better Core Web Vitals scores, higher Google rankings, lower bounce rates, and improved conversion. Compression is the highest-ROI SEO tactic.
50 images per batch
Process your entire product catalog, blog media library, or marketing assets in one batch. Parallel processing means no waiting between files.
