Choose imagesThis image resizer changes the dimensions and file size of any photo directly in your browser. Nothing is uploaded: the work happens on your own device, so a visa photo, a scanned document or a product shot never leaves your computer. It is free, with no watermark, no account and no cap on how many images you process.
How to resize an image
- 1
Add your images
Drag photos onto the drop zone, click to browse, or paste one from the clipboard with Ctrl+V. Add as many as you like — JPG, PNG, WebP, HEIC, GIF, BMP and AVIF are all supported.
- 2
Choose how to resize
Set exact pixel dimensions, scale by percentage, target an exact file size in KB or MB, or pick a preset such as the 2 × 2 inch passport photo.
- 3
Set the output format and quality
Keep the original format or convert to JPG, PNG or WebP, adjust quality, and pick a background color for padding or flattened transparency.

Resize an image to an exact file size (50 KB, 100 KB, 240 KB)
Government and job portals reject photos for being too large far more often than for being the wrong shape. Instead of guessing, open the File size tab and type your limit.
The resizer searches for the highest JPEG quality that still fits under the number you gave, holding your pixel dimensions steady wherever possible. Only when a target is unreachable at the lowest usable quality does it begin shrinking dimensions too — so you always keep the most detail the limit allows. A 5 MB phone photo drops under 240 KB in a couple of seconds.
US passport and visa photo requirements
The US is one of the few countries using a square photo. Printed passport photos are 2 × 2 inches (51 × 51 mm), which is 600 × 600 pixels at 300 dpi.
For the DS-160 online visa application and the Diversity Visa (green card) lottery, the uploaded photo must be square, between 600 × 600 and 1200 × 1200 pixels, in JPEG format, and 240 KB or smaller. The 240 KB ceiling is the single most common cause of a failed upload, and the CEAC tool frequently rejects an oversized file without explaining why.
Use the DS-160 preset: it crops to a perfect square, converts to JPEG and targets 240 KB automatically, so the file is compliant before you ever open the form.
JPG, PNG or WebP — which should you choose?
- JPG suits photographs and is what nearly every official upload expects, including the DS-160. It has no transparency, so transparent areas are filled with your chosen background color.
- PNG is lossless and supports transparency — right for logos, screenshots and graphics with text or hard edges, but much larger for photographs.
- WebP produces smaller files than JPG at equivalent quality and is excellent for your own website, but some older software and government forms will not accept it.
Quality between 75 and 85 is generally indistinguishable from the original while cutting file size substantially.
Upload sizes for US marketplaces
eBay asks for at least 500 px on the longest side and allows up to 12 photos free per listing; 1600 px enables zoom. Etsy recommends 2000 px on the shortest side for its zoom feature. Amazon Seller Central wants at least 1000 px on the longest side for zoom to activate, on a pure white background — use the “Pad to size” fit with white selected to place a product squarely on a white canvas.
For email, keeping total attachments under 20 MB clears most corporate filters; resizing a folder of photos to 1600 px wide and downloading them as a ZIP is usually enough.
US document photo specifications
Verify against the official source before submitting — these are the current published requirements.

| DS-160 visa upload | square | 600 × 600 to 1200 × 1200 px | max. 240 KB, JPEG | US Department of State |
| Diversity Visa (green card) lottery | square | 600 × 600 to 1200 × 1200 px | max. 240 KB, JPEG | US Department of State |
Why use this image resizer
- ✓Your images never leave your device. Most free resizers upload your file and hold it on their servers for hours. Here the processing runs in your own browser, so a visa photo or ID scan is never transmitted.
- ✓Exact file-size targeting. Ask for 240 KB and you get 240 KB at the best quality that fits — no trial and error against a quality slider.
- ✓One tool instead of four. Resize, compress, convert and batch-process in a single pass rather than hopping between separate pages.
- ✓Truly free and unlimited. No sign-up, no watermark, no daily cap — with no server doing the work there is nothing to meter.
- ✓Works offline. Once loaded, the page keeps working with your connection switched off.
- ✓Print-correct document photos. Presets write the proper print resolution into the file, so a 2 × 2 inch photo prints at 2 × 2 inches.
Frequently asked questions
Are my photos uploaded to a server?
No. Every image is processed in your browser. Files are read into memory on your own machine and never sent anywhere — you can disconnect from the internet after the page loads and it still works.
How do I get my DS-160 photo under 240 KB?
Choose the DS-160 preset, or open the File size tab and enter 240 KB. The tool finds the highest JPEG quality that fits under the ceiling while keeping the photo square and at least 600 × 600 pixels.
What size is a US passport photo?
2 × 2 inches (51 × 51 mm) — square, unlike the 35 × 45 mm rectangle used in most of Europe. At 300 dpi that is 600 × 600 pixels.
Is it safe to resize a passport or visa photo here?
Yes, and safer than with tools that upload. Because everything happens locally, your photo is never transmitted or stored on anyone else's server.
Can I convert HEIC photos from my iPhone?
Yes. Drop in a HEIC or HEIF file and it is decoded locally in your browser, then resized and saved as JPG, PNG or WebP.
Can I resize many images at once?
Yes. Add as many as you want, set your options once, and press “Resize all images”. Download the finished set as a single ZIP.
Will resizing hurt image quality?
Reducing pixel dimensions always discards some detail, but this tool downscales in stages rather than one large jump, which preserves noticeably more sharpness. At quality 80–85 the result is usually indistinguishable from the original.
