Resize an image.
Change dimensions by pixels or percentage, shrink a photo to an exact file size like 20 KB, or use one-tap presets for passport photos and document sizes — made for government portals, exam application forms, and job applications that reject anything but the exact size.
Your files are processed on your device and never uploaded.
Settings
We adjust quality and dimensions automatically to hit your size. Pick the output format under Export settings — JPG and WebP compress best.
Your photo is center-cropped to the exact size — no stretching — and saved as JPG. Set a max size for portals that reject files over a limit, like 50 KB.
Compress uses Export settings — set a Quality, or a Max file size to hit an exact target, then Compress.
Convert uses Export settings — pick an Output format (JPG, PNG, or WebP), then Convert.

Frequently asked questions
- How do I resize an image to 20 KB?
- Choose the "File size" option, type 20, leave the unit on KB, and tap Resize. The tool automatically balances quality and dimensions to land under 20 KB while keeping the image as sharp as possible.
- How do I make a passport-size photo for an online form?
- Choose "Presets", pick the size the portal asks for — passport 35×45 mm, 200×230 px, 3.5×4.5 cm, or a 512×512 avatar — and set a max file size like 50 KB if the form has an upload limit. Your photo is center-cropped to the exact dimensions with no stretching, then saved as JPG under your limit.
- Will resizing reduce my image quality?
- Shrinking dimensions keeps images looking crisp because we use high-quality scaling. Enlarging beyond the original size can look soft — no tool can add detail that was never captured.
- Are my photos uploaded to a server?
- No. The resizer runs entirely in your browser using your device’s own processor. Your photos never leave your phone or computer, and nothing is stored when you close the page.
- Can I resize multiple images at once?
- Yes — drop in as many as you like. The same settings apply to every image, and you can download them individually or all together.
- What formats are supported?
- JPG, PNG, and WebP. If you need to switch formats while resizing to a file size, pick JPG or WebP as the output — they compress far better than PNG.
