How to Use the Tools Step-by-Step
All our tools follow a simple 3-step workflow:
- Upload: Click the dashed file picker container or drag and drop your image files directly into the box.
- Adjust: Configure tool-specific sliders (like compression quality, blur radius, resize dimensions, rotation angles, or watermark text labels).
- Download: Click the primary black action button (e.g. "Compress & Download") to instantly save the file onto your device.
Why are some downloads failing?
Since all file operations are handled locally inside your browser, certain extensions or aggressive script blockers can sometimes interrupt Canvas operations. If your downloads do not trigger when you click the action button:
- Disable browser extensions that block canvas fingerprinting or scripts, as they may block canvas rendering.
- Ensure you are using a modern, HTML5-compliant browser (we recommend updated versions of Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge).
- Check if your device has enough free memory (RAM) and disk space to generate the processed file.
Is there a maximum image resolution or file size limit?
Because our scripts run entirely in your local RAM rather than on remote servers, we do not impose artificial file size limits. However, your device's physical hardware capacity (RAM) will determine the maximum resolution your browser can handle. Most modern computers and mobile phones can comfortably process image files up to 25MB or 8000x8000 pixels without performance lag. If you experience browser tabs freezing, try closing other heavy background programs or reducing your source image size before processing.
How does watermarking and cropping work?
Our Watermark tool lets you add custom text overlays. You can adjust opacity using a slider and select the alignment corner. Our Crop tool renders a draggable selection box over your uploaded image. When you move the corner handles and press "Crop", JavaScript measures the coordinates relative to the source image's actual pixel dimensions and outputs a cropped canvas rendering, preserving sharp lines.
