How to Create Flyers at imgresizr.com
Prepare your flyer design as a high-resolution image. Upload to imgresizr.com and use the Resize tool to set print dimensions at 300dpi resolution — for A4 this is 2480×3508px. If you are working from a lower-resolution image, use the Enlarge tool to upscale before resizing. Use the Enhance tool to ensure colours are vivid and will print accurately. Use the Caption tool to add text overlays — event details, prices, contact information, and calls to action. Make sure all key text is at least 14pt (equivalent at 300dpi) for readability when printed. For digital sharing, create a compressed version under 1MB using the Compress tool. This gives you both a print-quality and a share-ready version from one session.
Promotional Flyer Tips
- Include all essential W's: What, When, Where, and Why (the offer/benefit)
- One clear call to action is more effective than multiple competing actions
- Leave adequate margins (at least 3mm bleed) for print production
- Test that the flyer reads correctly on a mobile screen before distributing digitally
- QR codes are essential for physical flyers — link to your website or booking page
