How to use it
- Open Options and choose how to resize: by width, by height, by percentage or to an exact size.
- Drop your images into the box.
- Download the resized files. The new dimensions are shown beside each one.
Ways to resize
By width keeps the picture's proportions and sets the new width in pixels, and the height follows. By height works the same way from the other side. By percentage scales the picture, for example 50 percent halves both dimensions. Exact size sets both numbers, which can stretch the picture if the proportions differ.
Common sizes
Many websites show images about 1200 to 1600 pixels wide, and social posts often use 1080 pixels. Email and chat apps work well with images around 1000 to 1600 pixels wide. Smaller dimensions give much smaller files than quality changes alone.
Enlarging images
You can scale up with a percentage above 100, but making an image bigger does not add detail. The picture will look soft. Resize down whenever you can, and start from the largest original you have.
Format and privacy
Each image keeps its format, so a JPG stays a JPG and a PNG stays a PNG. HEIC photos can be converted to JPG first on the home page. Resizing runs in your browser, and your pictures are never uploaded.
Frequently asked questions
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. Your images are never sent to our server or to anyone else. You can confirm this in your browser's developer tools: the network tab shows no image data leaving the page.
Will resizing change the proportions?
Not when you resize by width, height or percentage. Only the exact size option can stretch a picture.
Can I resize many images at the same time?
Yes. The same setting is applied to every image you add, up to 100 per batch.
Does resizing reduce file size?
Yes, usually a lot, since there are fewer pixels to store.
