How to resize or compress an image
Choose your image
Select a JPG, PNG or WebP file from your device, or drop it into the image area. The preview shows your image before export.
Set dimensions and framing
Enter a width and height in pixels or choose a size preset. Keep original proportions to avoid changing the aspect ratio. Choose Fit whole image to keep every edge, or Crop to fill to remove the excess.
Choose a format and file size
Select JPG, PNG or WebP. For JPG and WebP, adjust quality or enter a maximum file size in KB. Export the image, check the reported size, and download the result.
Resize pixels or reduce KB: what is the difference?
Pixel dimensions describe how wide and tall a picture is. File size describes the storage it uses, in KB or MB. An application form may require both, such as a particular width and a file under 100 KB. Start with the requested dimensions, then adjust compression. Changing only the width does not guarantee a particular file size.
For a 50 KB, 100 KB or 200 KB target, choose JPG or WebP and enter that number in Maximum file size. The tool reduces quality while keeping your selected dimensions. If it cannot reach the limit, reduce the dimensions and export again. Check the downloaded file against the receiving website’s requirements.
Choose the right image format
| Format | Useful for | What to expect |
|---|---|---|
| JPG / JPEG | Photos and smaller attachments | Adjustable quality; no transparent background |
| PNG | Text, screenshots and transparent graphics | No lossy quality slider; may create larger files |
| WebP | Website images and transparent graphics | Adjustable quality; check the destination accepts WebP |
Convert WebP to JPG when a website only accepts JPEG, or PNG to JPG when transparency is unnecessary. Select a background colour before JPG export. Converting a compressed JPG to PNG does not restore detail already lost.
Crop images and use social size presets
Choose 1080 × 1080 for a square design, 1080 × 1350 for a portrait post, 1080 × 1920 for a vertical story, 1920 × 1080 for a landscape graphic, or 1280 × 720 for a thumbnail. These are available starting sizes, not a guarantee that every platform placement uses the same specification.
Crop to fill removes part of the source to match the selected frame. Adjust horizontal and vertical crop position to keep your subject visible. Fit whole image keeps the complete picture and can leave a background around it. For headlines, logos and layered layouts, open Design Studio.
Frequently asked questions
Can I compress an image to exactly 100 KB?
You can set 100 KB as a maximum target for JPG or WebP. The result may be smaller, and some images cannot meet the limit at the chosen dimensions. The tool reports this so you can reduce dimensions or choose a larger target.
Can I resize an image without losing quality?
Reducing dimensions removes pixels, and JPG or lossy WebP compression can remove detail. Start from the original, keep proportions and inspect the result. Enlarging a small photo cannot create missing detail; this tool does not offer AI upscaling.
Can I keep a transparent background?
Yes. Select PNG or WebP and enable Transparent background. Existing transparency is preserved when supported by the export format. This setting does not automatically remove a solid background from a photograph.
Does it resize images in bulk?
This page edits one image at a time. Download your result before choosing the next file.
What image sizes are supported?
Output can be up to 4096 pixels per side, within the 16-megapixel canvas limit. Large source images still need enough device memory.
Are my images uploaded or saved online?
No. Image processing happens in your browser. No account is needed and no watermark is added. Download the result before leaving or reloading the page.
