How to Compress Images for Hackaday

The quality of your project photography can make or break a DIY tutorial — readers need to see each step clearly, and finished project shots need to inspire them to try it themselves. Incorrect image sizing on Hackaday causes blurry thumbnails, poor display in search results, and rejection by platforms with strict upload requirements. This guide shows you how to get your images right every time.

Why Image Size Matters for Hackaday

Platforms like Hackaday apply their own compression to uploaded images. If you upload an image that is already at the correct size and quality, the platform's compression causes minimal quality loss. If you upload an oversized image, the platform downsizes it — often producing worse results than if you had sized it correctly yourself. Starting with the right dimensions gives you control over the final quality.

How to Compress Images for Hackaday — Step by Step

1. Open imgresizr.com in any browser — it works on desktop, tablet, and mobile with no installation required.
2. Click the Compress tab at the top of the page. For image resizing, use the Resize tab; for file size reduction, use the Compress tab.
3. Click Upload Image or drag and drop your Hackaday image onto the tool. Your image loads instantly in your browser without being sent to any server.
4. Enter the target width and height from the specifications table above. Click the padlock icon to lock the aspect ratio — this prevents your image from appearing stretched or squashed.
5. Click Compress to process your image. The result appears immediately for preview — check it looks correct before downloading.
6. If the file size is too large, run the result through the Compress tab to reduce it further without visible quality loss.
7. Click Download to save your correctly sized image. Upload it to Hackaday — it will display sharply, load quickly, and meet the platform's requirements.

5 Pro Tips for Hackaday Images

• Use consistent framing and background across all step photos — a consistent look makes your tutorial feel more professional and easier to follow
• Take step-by-step photos as you work — it is extremely difficult to recreate in-progress shots after a project is complete, and these are the images readers value most
• Photograph your finished project from multiple angles — include close-up detail shots showing material quality, joinery, or finish alongside wide establishing shots
• Include a before-and-after comparison image — these perform exceptionally well on Pinterest and drive significantly more saves and repins than single images
• Label photos with step numbers directly in the image using the Caption tool — this is especially useful when sharing on platforms where captions may be hidden or truncated

Frequently Asked Questions

How many photos should a Hackaday tutorial have?

A complete DIY tutorial should include: 1 hero shot of the finished project, photos for every significant step (at minimum every 2–3 steps), close-up detail shots of key techniques or materials, and a before-and-after comparison if applicable. More photos generally produce better engagement and fewer questions in comments, as readers can follow along accurately.

What image size should I use for my Hackaday photos?

For Hackaday, step-by-step instructional photos work best at 800 × 600 px — clear enough to show detail but small enough to load quickly. Hero / feature images should be 1200 × 628 px for blog posts. For Pinterest, create portrait images at 1000 × 1500 px (2:3 ratio) — vertical pins perform significantly better than square or landscape formats on Pinterest.

Should I watermark my Hackaday project photos?

Yes, watermarking DIY project photos is recommended if you are publishing original work. Place a subtle watermark with your blog URL or logo in a corner of the image. This protects your attribution if images are shared without credit. Use the Caption or Watermark tools at imgresizr.com to add a professional-looking watermark to your project photos.
