Built for Everyone Who Works with Images

Whether you sell on Amazon or post on Instagram, PixelBatch has a dedicated tool for your exact use case.

🛒 E-Commerce Sellers

Stop getting listings rejected on Amazon, Walmart, and Shopify. Each platform has strict image specs — wrong background color, wrong aspect ratio, wrong file size. PixelBatch enforces all three automatically, in bulk, for free.

📸 Photographers & Creators

Resize entire photo shoots in seconds. Convert RAW exports to optimized JPGs or WebP for fast web delivery. Batch compress client galleries without uploading them to a third-party server — your work stays private.

📱 Social Media Managers

Prepare content for every platform without separate apps. Resize for Instagram Posts, Stories, and Reels. Compress YouTube thumbnails under 2MB. Batch process an entire content calendar in one sitting.

🏛️ Government Document Applicants

Creating a US Passport, DS-160 Visa, or DV Lottery photo requires biometric precision — 600x600px, under 240KB, white background. Our tool enforces the exact State Department specification without uploading your face to any server.

⚡ Web Developers

Optimize images before deployment. Convert entire asset libraries to WebP or AVIF for Core Web Vitals compliance. Compress to exact KB targets to hit Lighthouse performance scores. No build pipeline required.

🔒 Privacy-Conscious Users

Medical documents, legal files, unreleased product photos, personal IDs — some images should never leave your device. PixelBatch uses WebAssembly to process 100% locally. We have no upload server by design, not just by policy. Read our technical blog for details.

Why Client-Side Processing is the Future

If you've ever searched for a "free image resizer," you've likely used cloud-based tools like TinyPNG, iLoveIMG, or Canva. While popular, they come with significant hidden costs regarding your privacy and workflow speed.

❌ The Old Cloud Model

Cloud tools require you to actively upload your files to their remote servers. You wait for the upload, wait for the server to process it, and wait to download it again. Worse, your highly sensitive documents (like IDs, bank statements, or unreleased product designs) are now sitting on a third-party server. Once you process 5 or 10 images, they hit you with a hard paywall forcing a monthly subscription.

✅ The PixelBatch Model

PixelBatch utilizes advanced browser WebAssembly to process every single pixel locally on your own computer's hardware. Your images never leave your device. Because we don't have to pay for expensive cloud computing servers, we don't pass those costs on to you. No uploads, total privacy, instantaneous processing, and no artificial bulk limits.

The Privacy-First Feature Set

Everything you need to optimize your digital assets securely.

Zero Uploads

100% offline processing inside your browser. Protects sensitive documents from server scraping.

Unlimited Bulk Edit

Drop 1 photo or 500 photos. Resize entire e-commerce catalogs simultaneously without hitting paywalls.

Smart Auto-Crop

Advanced 'contain' and 'cover' algorithms ensure your products are never distorted when changing aspect ratios.

Lossless Compression

Target exact KB limits (e.g., 50KB or 2MB) while maintaining maximum visual fidelity for crisp web loading.

Frequently Asked Questions

Is PixelBatch really free for unlimited use? ▼

Yes. Because we process images locally on your device using WebAssembly (Client-Side), we have zero cloud server costs. This allows us to offer unlimited bulk image resizing entirely for free, with no watermarks and no signups.

Do you keep a copy of my photos? ▼

Absolutely not. Your privacy is 100% guaranteed. PixelBatch does not have an upload server. Your images never leave your computer or phone; the processing happens directly inside your web browser.

How does PixelBatch compare to TinyPNG or iLoveIMG? ▼

Cloud-based tools like TinyPNG or iLoveIMG require you to upload your files to their servers, which poses a privacy risk for sensitive documents. They also frequently hit you with paywalls or daily limits. PixelBatch processes offline in your browser, offering faster speeds, total privacy, and zero paywalls.

Which e-commerce platforms do you have presets for? ▼

We have dedicated, one-click optimization tools for Amazon FBA, Walmart Marketplace, and Shopify. These tools automatically enforce the strict aspect ratios, padding, and file size limits required by each platform to prevent listing rejections.

What image formats does PixelBatch support? ▼

PixelBatch supports JPG, PNG, WebP, AVIF, and HEIC (iPhone format) as inputs. You can output to JPG, PNG, or WebP. HEIC files from iPhones are automatically converted to JPG or WebP for universal compatibility.

Does PixelBatch work on mobile? ▼

Yes. Because PixelBatch is 100% browser-based, it works on any device — iPhone, Android, iPad, Mac, Windows, or Linux. No app download is required. Simply open pixelbatch.io in any modern browser and start processing.

Can I compress images without losing quality? ▼

Yes. PixelBatch uses smart compression algorithms that can reduce file sizes by 40–80% while maintaining visually lossless quality. You can also set a target file size (e.g., compress to exactly 100KB) and our engine will find the optimal quality setting automatically.

How many images can I resize at once? ▼

There is no limit. You can drop 1 image or 500 images at once. PixelBatch processes them simultaneously using your device's CPU, so larger batches process in parallel. There are no daily quotas, no per-image charges, and no paywalls at any batch size.

Is PixelBatch better than Photoshop for bulk resizing? ▼

For bulk resizing tasks, yes. Photoshop's batch actions require setup time and a paid subscription. PixelBatch does the same bulk operations in seconds with zero setup, zero cost, and no software installation. For complex photo editing and retouching, Photoshop is still the professional tool — but for resizing, format conversion, and compression, PixelBatch is significantly faster.
