What is the Image Resizer?
Every platform wants a different picture size: Facebook covers, Instagram posts, YouTube thumbnails, job portals and website banners. This image resizer changes the width and height of your photos in pixels or by percentage, with ready-made presets for the most common sizes.
When the new shape is different from the original, you decide what happens: keep the whole picture and fit it inside, fill the frame and crop the edges, or stretch it. You can resize many photos at once and save them as JPG, PNG or WebP.
Type the width and height you need or pick a preset such as Facebook cover or Instagram post. Keep the aspect ratio locked to avoid stretching, then download.
When to use it
- Social media posts and covers that look sharp and are not cut off.
- Product photos with one uniform size for a shop.
- Smaller images for email and messaging.
- Exact pixel sizes asked by application forms.
Tips for the best result
- Type only the width (or only the height) to keep the original proportions automatically.
- Making a small photo bigger cannot add real detail; start from the largest original you have.
- For a strict file size limit, use one of the Compress Image to KB tools after resizing.
Questions
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it much larger than the original can look soft, because new detail cannot be invented.
What is the best size for a Facebook post?
1200×630 px works well for link and photo posts, and 1080×1080 px for square posts.
Can I resize by percentage?
Yes. Choose Percentage and type a value, for example 50 to make the image half its size.
Is the Image Resizer free?
Yes. It is completely free with no sign-up and no watermark. Use it as often as you like.
