Bulk Image Resizer & Watermarker Script
Resize and watermark hundreds of images at once, automatically, to your exact specifications.
The Problem
Resizing and watermarking product photos or portfolio images one at a time in an editor doesn't scale once you're dealing with hundreds of files that all need the same treatment.
About this problem
Resizing and watermarking one image takes seconds, but doing it for hundreds quickly becomes unmanageable. A script applies identical rules to every file, including resizing to fixed dimensions or a maximum edge, positioning the watermark and handling different aspect ratios and formats consistently.
People usually come to this when preparing product catalogues, portfolios or event photos for a website or marketplace, where every image must meet the same size limits and carry the same mark.
What's Included
- A script that resizes a whole folder of images to your exact dimensions/rules
- Applying a text or logo watermark at the position and opacity you specify
- Preserving image quality and format sensibly during processing
- Output as a ready-to-use folder or ZIP
What's NOT Included
- Design work on the watermark/logo itself (you provide it, or it can be scoped separately)
- Processing video files (images only)
- Ongoing automatic processing of new uploads unless set up as a standing tool
How It Works
- I agree the target sizes, resize rules, formats and watermark placement and opacity with you.
- I write a script, typically in Python with an image library, that processes a folder of images.
- I resize each image while keeping its aspect ratio or cropping, according to your rules.
- I apply your text or logo watermark at the chosen position and opacity.
- I save each result in an output folder using sensible compression to preserve quality.
- I test on a sample batch including different orientations and formats, then package the result.
In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.
Frequently Asked Questions
- How do I resize and watermark many images at once?
- A script can process a whole folder with the same rules. I build it around your size and watermark requirements.
- Will image quality suffer?
- I choose compression settings to keep quality sensible, though any resize or recompression changes the file to some degree.
- Can you design my watermark?
- Not as part of this. You supply the logo or text, or design work can be scoped separately.
- Does it handle videos?
- No. Images only.
- Can it process new uploads automatically?
- Not unless it is set up as a standing tool, which is a separate piece of work.
- Are my original files changed?
- No. Output goes to a separate folder.
