Set exact pixel dimensions or pick from common presets. Scale screenshots for social media, email, presentations, or docs â without losing sharpness. Works in your browser or runs locally on Mac & Windows.
Common screenshot sizes
Not sure what dimensions you need? These cover most situations.
| Size (px) | Name | Best for |
|---|---|---|
| 1920 x 1080 | Full HD | Presentations, blog headers, desktop wallpapers |
| 1280 x 720 | HD / 720p | Email embeds, smaller blog images, Notion pages |
| 800 x 600 | SVGA | Documentation, help center articles, README files |
| 1200 x 630 | OG Image | Social media link previews (Facebook, LinkedIn, Twitter) |
| 1080 x 1080 | Square | Instagram posts, social media thumbnails |
| 1080 x 1920 | Portrait | Instagram Stories, TikTok thumbnails, mobile screenshots |
How to resize a screenshot
Three steps. No Photoshop required.
Open your screenshot
Paste with âV or capture directly with the built-in screenshot tool. Drag an image file from Finder if you prefer. The screenshot lands on the canvas instantly â no import wizard, no file picker unless you want one.
Pro tip: Mac screenshots taken with ââ§4 are already on your clipboard. Hit âV in ScreenshotEdits and you're editing within a second of capturing.
Set your target dimensions
Type in the exact width and height you want, or choose from built-in presets for common sizes. The aspect ratio locks by default so your screenshot scales proportionally. Unlock it if you need non-standard proportions â just know that stretching is rarely what you want.
Pro tip: Need a specific width but don't care about height? Enter just the width with aspect ratio locked and the height calculates automatically.
Export at the right size
Save as PNG for pixel-perfect quality or JPEG for smaller files. The resize happens at export time, so you can try different dimensions without starting over. Copy to clipboard with âC to paste directly into Slack, email, or your docs.
Pro tip: For retina-ready images, export at 2x. If your target display size is 600px wide, export at 1200px. Text and UI elements stay razor sharp on high-DPI screens.
When you need to resize
Screenshots are almost never the right size for where they end up. Your retina Mac captures at 2880px wide, but your blog needs 1200px, your email needs 600px, and LinkedIn wants something else entirely. Resize handles all of it.
Social media sizing
Every platform wants different dimensions. LinkedIn banners, Twitter cards, Instagram stories â they all have their own pixel requirements. Resize once, post everywhere, without the cropping surprises.
Email-friendly dimensions
Most email clients cap image width around 600px and some choke on anything over 1MB. Resize your screenshots down before embedding them and your emails actually render properly across Outlook, Gmail, and Apple Mail.
Presentation slides
A 2880x1800 retina screenshot dropped into Google Slides or Keynote looks great â until you realize the file is 8MB and the presentation takes forever to load. Resize to 1920x1080 and your slides stay sharp without the bloat.
Documentation
Help docs and README files need screenshots that are consistent in width. When one image is 1400px and the next is 900px, it looks sloppy. Resize them all to the same width and your docs look like someone who cares wrote them.
Resize vs crop â what's the difference
People mix these up constantly. They do very different things, and picking the wrong one means either a stretched image or a missing section. Here's when to use each.
Resize
- Keeps the entire image â nothing gets cut off
- Changes overall dimensions proportionally
- Best for: fitting images into specific containers or reducing file size
Crop
- Removes edges and keeps a selected region
- Maintains original resolution within the cropped area
- Best for: focusing on a specific area or removing unwanted borders
Bottom line: Need the whole screenshot but smaller? Resize. Need just part of the screenshot at full quality? Crop. And often you'll want both â crop first to the relevant area, then resize to your target dimensions.
Tips for better resizing
Resizing seems simple, but a few small habits make the difference between crisp images and blurry ones.
Lock the aspect ratio
Unless you specifically need to stretch an image, keep the aspect ratio locked. A 16:9 screenshot squeezed into 4:3 looks wrong immediately â even people who don't know the term 'aspect ratio' will notice something's off.
Think about retina
Most Macs capture screenshots at 2x resolution. A screenshot that's 2880px wide will display at 1440px on a retina screen. If you're resizing for web, export at 2x your CSS dimensions to keep text crisp.
Smaller files load faster
A 2880x1800 PNG can easily be 4-5MB. Resize to 1440x900 and it drops to under 1MB. For docs and emails, that difference matters more than you'd think â especially on slower connections or mobile.
Stay consistent across a set
If you're creating screenshots for a help center or product docs, pick one width (800px or 1200px work well) and stick with it for every image. Consistency makes your content look polished without any extra design effort.
More than just resize

Frequently asked questions
Does resizing reduce image quality?
Downscaling (making smaller) preserves quality well. Upscaling (making larger) can introduce softness since new pixels need to be interpolated. For best results, start with the largest version you have.
Can I resize to exact pixel dimensions?
Yes. Enter any width and height in pixels. You can lock the aspect ratio to scale proportionally, or unlock it to stretch to exact dimensions.
Does my screenshot get uploaded anywhere?
No. ScreenshotEdits runs in your browser or locally on your desktop. Your screenshots never leave your computer â no cloud processing, no servers, no tracking.
What's the difference between resize and crop?
Resize changes the overall dimensions of the entire image â everything scales up or down. Crop removes parts of the image you don't need, keeping the remaining area at its original resolution.
Can I use this for free?
Yes. All features including resize are free. The free version adds a small watermark to exports. Free in your browser with 3 exports/day. Desktop app €19 one-time to remove watermark.
How do I resize for retina displays?
Export at 2x your target display size. If the image will show at 400x300 on screen, export at 800x600. ScreenshotEdits supports 1x, 2x, and 3x export scales.
Can I resize multiple screenshots at once?
Currently ScreenshotEdits handles one image at a time. But the workflow is fast â paste, resize, export, repeat. Most people finish a batch of ten screenshots in under two minutes.
