Free Marketing & Design Tools
Resize images for social media, build campaign tracking links, and generate brand color palettes — all in your browser. No upload. No signup. No cost.
Social Media Image Resizer
Resize any image to the exact dimensions required by Instagram, YouTube, Facebook, LinkedIn, X, Pinterest or WhatsApp — with crop, rotate, and quality control.
How to Use
- Click the drop zone (or drag an image file onto it) to load your image from your device.
- Choose a Platform / Size from the dropdown — the canvas resizes instantly.
- Pick a Fit Mode: Cover fills the whole frame (crops edges), Contain keeps the full image visible (adds background).
- Use the rotate, flip, and zoom controls to fine-tune framing.
- Select Output Format (JPG is smallest, PNG supports transparency, WebP is smallest of all) and adjust the quality slider.
- Click Download Image — the file saves directly to your device.
Pro Tips
- Use JPG at 80–90% for photos to keep file size small without visible quality loss.
- Use PNG only when you need transparent backgrounds (logos, cut-outs).
- Use WebP for website images — it can be up to 30% smaller than JPG at the same quality.
- For YouTube thumbnails, keep text in the safe zone (avoid the bottom-right corner, where the duration badge appears).
UTM Tracking Link Builder
Create UTM-tagged URLs so Google Analytics and other platforms can tell you exactly which campaign, channel, and ad creative drove each click.
How to Use
- Paste the destination URL (for example
https://toolsa2z.com/pricing). - Click a preset button (Facebook, Google Ads, Newsletter, etc.) to auto-fill the source and medium.
- Enter your Campaign Name — use a consistent naming style like
diwali_sale_2026. - Optionally add Campaign Term (paid keywords) and Content (for A/B testing).
- Click Generate Tracking URL, then Copy URL to use it in your ads, emails, or social posts.
Pro Tips
- Always use lowercase for source and medium —
Facebookandfacebookcount as two different channels in Analytics. - Use _ (underscore) instead of spaces. Never use spaces.
- Keep a UTM spreadsheet in your team so campaign names stay consistent across people.
- Use utm_content to A/B test the same ad with two creatives.
Brand Color Palette Generator
Generate harmonious color palettes from a single base color, then verify text readability against the WCAG contrast standard.
How to Use
- Pick your Base Color — usually the primary color from your logo or brand.
- Choose a Palette Type: Analogous for calm designs, Complementary for high contrast, Triadic for a balanced multi-color palette, Monochromatic or Shades for minimal brands.
- Click Generate Palette to refresh with the latest base color.
- Click any color swatch to copy its HEX code to your clipboard.
- Use the Contrast Checker below to confirm your text is readable against any background.
- Click Export as CSS or Export as JSON to grab the full palette for your design or code.
Click any swatch to copy its HEX code individually.
WCAG Contrast Checker
Pro Tips
- Aim for a contrast ratio of at least 4.5:1 for body text and 3:1 for large text (WCAG AA).
- Use one primary color, one accent, and 2–3 neutrals — don’t use all 5 colors equally.
- Test the palette in both light and dark mode before finalizing your brand.
Frequently Asked Questions
Are these marketing and design tools free?
Yes. All three tools — image resizer, UTM link builder, and color palette generator — are 100% free with no signup, no watermark, and no usage limits.
Do my images get uploaded to a server?
No. All processing happens locally in your browser using JavaScript and the HTML5 Canvas API. Your images never leave your device, making these tools safe for confidential creative work.
What image sizes should I use for Instagram, YouTube, and Facebook?
Instagram Post: 1080×1080, Instagram Story/Reel: 1080×1920, Facebook Post: 1200×630, YouTube Thumbnail: 1280×720, LinkedIn Post: 1200×627, Pinterest Pin: 1000×1500. All of these are built-in presets in our resizer.
What is a UTM parameter and why should I use one?
UTM parameters are tags added to a URL that tell Google Analytics (and other tools) where each click came from — Facebook, a newsletter, a Google Ad, etc. Without them, all your traffic shows up as “direct” or “referral” and you can’t measure which campaign actually worked.
How do I choose the right brand colors?
Start with one base color (usually from your logo), then use a color harmony rule such as analogous, complementary, or triadic to generate matching colors. Always verify readability with the WCAG contrast checker included in our palette tool.
