TweakNow ImageConverter batch-converts image files between various formats, including HEIC/HEIF, AVIF, WEBP, GIF, JPEG, JPEG XL, PNG, and can compile them into a PDF. It also allows you to resize, watermark (with text, image, or QR code), and adjust multiple images simultaneously.

What It Does

TweakNow ImageConverter quickly converts your folder full of images to the desired format. Whether you're generating web‑friendly JPEGs or packing photos into a single PDF, it handles batch processing, resizing, metadata retention, watermarking with text/images or QR codes, and even lets you define a custom enhancement order.

Why You Might Want It

Think of it as a time-saver when preparing photos for websites, presentations, or archives. Instead of opening and saving each file manually, you set up your rules once, format, size, watermark, and let it rip. Handy if you handle marketing graphics, product shots, screenshots, or want to quickly watermark social media pics in bulk.

Features We Like

TweakNow ImageConverter keeps it simple with a single-window interface. You drag in files or folders, pick output settings, queue optional enhancements, and run. It supports modern formats, such as AVIF, JPEG XL, and HEIC, alongside classics like JPEG, PNG, and GIF. Watermark options include text, image overlays, or embedding a QR code. You can resize by percentage or to exact dimensions.

Limitations & Downsides

The UI is barebones, with no live preview window while tweaking settings. Functionality is focused, so it lacks advanced editing tools such as filters, cropping, or color correction. The trial is limited to one week, and support is minimal.

Ideal Use Cases

It's best for folks who want fast conversion and watermarking on Windows. Great for photo bloggers, small-business marketers, teachers, or anyone who batches images and doesn't need a full-blown image editor. If you need editing beyond resizing and watermarking, a free tool like IrfanView or ShareX may suit you better.

Geek Verdict

TweakNow ImageConverter is lean, reliable, and efficient for tasks such as converting or watermarking images in bulk on Windows. It's streamlined and priced modestly; don't expect fancy photo editing or long trials. For what it does, it's practical, efficient, and easy to master.
