Can I use Shrinkpad for free?

Yes! Shrinkpad offers a free tier that lets you compress up to 10 files per batch with standard compression settings. It's perfect for trying out the app or occasional use. For unlimited batch processing, all formats, and advanced controls, you can upgrade to a Personal or Team license.

What file formats does Shrinkpad support?

Shrinkpad supports a wide range of formats. For images: JPEG, PNG, WebP, HEIC, TIFF, GIF, and BMP. For videos: MP4, MOV, M4V, AVI, and MKV. We also support 30+ RAW camera formats including CR2, CR3 (Canon), NEF (Nikon), ARW (Sony), DNG, and many more.

Does Shrinkpad support video compression?

Yes! Shrinkpad can compress videos just like images. Simply drag and drop your video files or folders, and Shrinkpad will reduce their file size while maintaining visual quality. Video compression is available on Personal and Team licenses.

How many files can I process at once?

With the free tier, you can process up to 10 files per batch. With a Personal or Team license, there's no limit — you can process hundreds or even thousands of files in a single batch.

Are my files uploaded to the cloud?

No, never. All compression happens 100% locally on your Mac. Your files never leave your device, and we have zero access to your images or videos. This makes Shrinkpad perfect for sensitive or confidential content.

Does it work on my Mac?

Shrinkpad runs natively on macOS 13 Ventura and newer, with full support for both Apple Silicon (M1, M2, M3, M4) and Intel Macs. The app is optimized to take full advantage of Apple Silicon performance.

Can I use Shrinkpad on multiple devices?

The Personal license ($14) is valid for 1 device. If you have multiple Macs or work with a team, the Team license ($35) covers up to 10 devices. You can transfer your license to a new device if you replace your computer.

Is there a refund policy?

Yes, we offer a 7-day money-back guarantee, no questions asked. If you're not satisfied with Shrinkpad for any reason, simply email support@shrinkpad.app within 7 days of your purchase with your purchase date and order details, and we'll process a full refund.

How to Convert Images to WebP on Mac (Batch Conversion)

You run your website through PageSpeed Insights. It comes back with the same suggestion it's been giving you for years: "Serve images in next-gen formats."

You know you should be using WebP. Your images are still JPG and PNG because converting them has always been annoying. Let's finally fix that.

Why WebP? The Numbers.

WebP isn't just a Google pet project anymore — it's the practical standard for web images:

WebP vs JPG: 25-35% smaller at equivalent visual quality.
WebP vs PNG: 26% smaller for lossless. Up to 3x smaller for lossy.
Browser support: 97%+ globally. Every modern browser has supported it since at least 2020. The "but Safari doesn't support it" excuse ended with Safari 16 in 2022.

Google uses image format and size as a ranking signal through Core Web Vitals (LCP specifically). Switching to WebP is one of the easiest SEO wins available.

Option 1: cwebp Command Line Tool

Google provides a dedicated command-line tool:

brew install webp

Single file:

cwebp -q 80 photo.jpg -o photo.webp

Batch (bash loop):

for f in *.jpg; do cwebp -q 80 "$f" -o "${f%.jpg}.webp"; done

This works great if you're comfortable with Terminal. The quality is excellent — Google made both the format and the conversion tool. The downside: no preview. You're picking a quality number and hoping for the best until you open the output file.

Option 2: Use an Image Editor

Photoshop: File → Export As → WebP (added in Photoshop 23.2).
GIMP: File → Export As → change extension to .webp.

Both work fine for one-off conversions. Neither is practical for "convert my entire blog's 200 images."

Option 3: Batch Convert with ShrinkPad

For bulk conversions with visual feedback, a dedicated tool makes the difference.

Blog Migration Test

Converting 150 blog images (JPG + PNG, 340MB) to WebP:

cwebp bash loop: 28 seconds, no preview, some files over-compressed.
ShrinkPad: 14 seconds, with quality preview. Total output: 89MB (74% reduction).

Here's the workflow:

Select your images: Grab your website's entire images/ folder. JPGs, PNGs, or a mix — ShrinkPad handles both.
Choose WebP as output: One click to set the target format.
Adjust quality: 80% is the sweet spot for web images. The live preview lets you spot any artifacts before committing.
Convert: Multi-threaded processing. Your folder structure is preserved, so images/blog/ stays organized as images/blog/.

ShrinkPad handles JPG→WebP and PNG→WebP differently under the hood (lossy vs lossless), so transparent PNGs keep their transparency automatically.

Stop uploading your files to the cloud.

Compress images and videos locally on your Mac. Fast, private, and no internet required.

WebP vs AVIF: Should You Go Even Further?

AVIF is the next evolution: roughly 20% smaller than WebP with better quality at low bitrates. Browser support is at ~93% globally — solid, but not quite universal yet.

Recommendation: Use WebP as your primary format today. If you want bleeding-edge performance, add AVIF as a progressive enhancement using the <picture> element:

<picture>
  <source srcset="photo.avif" type="image/avif">
  <source srcset="photo.webp" type="image/webp">
  <img src="photo.jpg" alt="Fallback">
</picture>

ShrinkPad supports both WebP and AVIF output, so you can generate both formats from the same source images in a single session.

Fastest SEO Win Available

Switching to WebP is the lowest-effort, highest-impact performance optimization for any website. Convert once, load faster forever.
