Learn how to resize, crop, add filters, watermarks, and export images for social media platforms in this comprehensive tutorial.
Whether you’re creating content for Instagram, designing a YouTube thumbnail, or preparing images for your blog, having the right tools makes all the difference. This comprehensive guide will walk you through every feature of our free online image editor, helping you create professional-quality images in minutes.
Getting Started: Uploading Your Image
The first step is getting your image into the editor. We’ve made this as simple as possible with two convenient methods:
- Drag and Drop: Simply drag your image file from your computer and drop it onto the upload area
- File Browser: Click the “Choose File” button to browse and select an image from your computer
Supported formats include JPG, PNG, WebP, GIF, and more. Maximum file size is 50MB, which covers virtually all use cases from social media posts to high-resolution prints.
Resizing Images: Perfect Dimensions Every Time
One of the most common tasks in image editing is resizing. Our editor offers two powerful approaches:
Manual Resize
Enter custom width and height values (in pixels) to resize your image to exact specifications.
Social Media Presets
Why guess at dimensions? Choose from pre-configured sizes optimized for every major platform:
- Instagram/Facebook/X Square: 1080 × 1080px – Perfect for feed posts
- Instagram/X Vertical: 1080 × 1350px – Ideal for portrait posts
- Instagram/TikTok/Facebook Stories/Reels: 1080 × 1920px – Full-screen vertical content
- Instagram/Facebook Landscape: 1080 × 566px – Widescreen posts
- Facebook/LinkedIn Post: 1200 × 630px – Link previews and shared posts
- YouTube Thumbnail: 1280 × 720px – HD video thumbnails
- YouTube Channel Banner: 2560 × 1440px – Channel artwork
- X Header: 1500 × 500px – Profile header image
- Pinterest Pin: 736 × 1128px – Optimized pins
Fit Modes
When resizing to different aspect ratios, choose how your image should fit:
- Stretch: Stretches the image to fill the new dimensions (may distort the image)
- Contain: Fits the entire image within the new dimensions, adding padding if needed
When using “Contain” mode, you can select a custom padding color to match your brand or design.
Cropping: Focus on What Matters
The crop tool lets you select exactly which part of your image to keep:
- Click the “Start Crop” button in the Edit panel
- Drag the crop handles to select your desired area
- See the exact crop dimensions displayed in real-time
- Click “Apply Crop” to confirm, or “Cancel” to discard
The crop tool maintains high quality and provides pixel-perfect control over your selection.
Rotating and Flipping
Sometimes you need to adjust the orientation of your image. The editor provides quick controls for:
Flip Vertical: Flips the image upside down
Rotate Left: Rotates the image 90° counter-clockwise
Rotate Right: Rotates the image 90° clockwise
Flip Horizontal: Creates a mirror image (left becomes right)
Filters and Effects: Enhance Your Images
Transform the look and feel of your images with professional-quality filters and manual adjustments.
Filter Presets
Apply Instagram-style filters with a single click:
- Artistic: Creative color enhancement
- Original: No filter applied
- Grayscale: Classic black and white
- Sepia: Warm vintage tone
- Vintage: Retro film look
- Vivid: Boost colors and contrast
- Soft: Gentle, dreamy effect
- High Contrast: Bold, dramatic look
- Cinematic: Movie-grade color grading
- Clarendon: Instagram-inspired clarity
- Juno: Bright and vibrant

Manual Adjustments
Fine-tune your image with precision controls:
- Brightness: Make your image lighter or darker (0-200%)
- Contrast: Adjust the difference between light and dark areas (0-200%)
- Saturation: Control color intensity (0-200%)
You can combine preset filters with manual adjustments for complete creative control. If you modify a preset, the editor notifies you and allows you to clear the preset to start fresh.
Adding Watermarks: Protect Your Work
Protect your images and build brand recognition by adding watermarks:
Text Watermarks
- Enter your custom text (copyright notice, brand name, website, etc.)
- Choose font size (10-100px)
- Select text color using the color picker
- Adjust opacity (0-100%) for subtle or prominent watermarks
- Position the watermark anywhere on your image
Exporting Your Image
When you’re happy with your edits, it’s time to download your masterpiece.
Format Options
- PNG: Lossless quality, supports transparency, larger file size – perfect for graphics and logos
- JPEG: Smaller file size, no transparency, adjustable quality – ideal for photos and web use
- WebP: Modern format with excellent compression and quality – best for modern websites
Quality Settings
For JPEG and WebP formats, adjust the quality slider (1-100%) to balance file size and image quality. Higher values mean better quality but larger files.
Download Multiple Sizes
Save time by exporting your image in multiple sizes at once. Click “Download Multiple Sizes” to get:
- The original size of your image
- The original size of your image multiplied by 2
- The original size of your image multiplied by 3
All sizes are packaged in a convenient ZIP file.
