Are these image tools really free?

Every tool in this category is free, runs in the browser, and needs no sign-up or credit card. Files are processed client-side in most cases, the image never leaves the device. Extremely large files (over ~50 MB) may lag on older laptops because of browser memory limits, so break the work into smaller passes.

What's the best format for web images in 2026?

WebP is the practical default, it ships to 96% of browsers and saves roughly 25-35% over JPG at the same visual quality. Use convert-png-to-webp when the source has transparency, and jpg-to-webp when it doesn't. Stick with PNG for icons under 100×100 px or lossless illustrations.

How do I compress an image without losing visible quality?

Compression always trades some quality for size. compress-image exposes a quality slider: 80 is the sweet spot for photos, 90 for screenshots with text. For a size win without visible loss, convert to WebP first, the format is ~25% smaller than JPG at matching quality.

Can I resize images in bulk?

These tools process one file at a time, which works for 10-30 images. For a Shopify catalog of 500 photos, handle the first 20 heroes with image-resizer and run a local script for the rest. The upside of one-at-a-time is precision, the exact pixel output is visible before committing, catching mistakes a batch script would propagate.

Are my uploads private?

Most tools run client-side, the image is processed in JavaScript and never uploaded. Detection-based tools like blur-face-in-image may send the file to a server model; it's deleted after processing. For sensitive material (medical, legal, unreleased product shots), inspect the browser network tab before uploading.

What's the difference between resizing and cropping?

Resizing shrinks or enlarges the full frame, a 3000×2000 photo at 50% becomes 1500×1000, still showing everything. Cropping cuts away part of the image for a new aspect ratio. Use image-resizer when the whole picture should be smaller, and image-cropper when the frame itself is wrong.

Image Tools

This category collects the image-editing jobs that break up a designer’s or store owner’s day, resizing product shots to 1200px, compressing a 4 MB hero to under 300 KB, converting PNG exports to WebP, stamping a watermark before publishing. A Shopify owner prepping 30 product photos for a homepage relaunch can run the whole sequence here without opening Photoshop.
