Reduce passport and ID photo size to under 1 MB
Online applications for passports, visas, universities and public services often reject photos that are too large, most commonly above 1 MB, and sometimes above 500 KB or 200 KB. A photo straight from a modern phone can weigh 3–8 MB, so it has to be reduced before it can be uploaded.
This page is preset for document photos: images are saved as JPG at 70% quality, resized to a maximum of 800 px and kept under 1 MB. If your portal asks for an even smaller file, choose 500 KB or 200 KB under Max file size and each photo is adjusted until it fits. In Vietnamese this is often searched as "giảm dung lượng ảnh thẻ" or "nén ảnh dưới 1MB".
Photo size vs file size: 3×4 and 4×6 explained
Sizes such as 3×4 cm and 4×6 cm describe the printed shape, not the file size. 3×4 cm (a 3:4 ratio) is used for most application forms and CVs, while Vietnamese passport applications usually ask for 4×6 cm (a 2:3 ratio). Crop to the right shape first with the Passport / ID preset in our Image Resizer, then compress the result here.
- 3×4 cm at 300 DPI: 354 × 472 pixels.
- 4×6 cm at 300 DPI: 472 × 709 pixels.
- Typical online limits: under 1 MB, sometimes under 500 KB or 200 KB.
Why this image compressor is private
Most online compressors upload your photos to a server, process them there and send them back. This one never uploads them. The compression engine runs inside your browser using background Web Workers: your images are read from your device into memory (RAM), compressed by your own processor and saved straight to your downloads folder. Nothing is stored, and closing the tab clears everything. It also means no upload wait, no daily quota and no server file-size cap.
Frequently asked questions
How do I reduce a photo to under 1 MB?
Add the photo on this page and click Compress all. The preset saves it as JPG, resizes it to 800 px and lowers the quality further if needed until the file is under 1 MB. The new size appears next to the original before you download.
Will a compressed photo still be accepted?
Usually yes: portals check the format, file size and pixel dimensions, and a face stays sharp at 800 px. If your form requires a larger minimum resolution, choose a bigger Resize option and keep the 1 MB limit.
Is it safe to compress my ID or passport photo online?
On this site, yes. Your photo is processed inside your browser and is never uploaded, so it cannot be stored or reused. Be careful with tools that require uploading identity photos to their servers.
Why does my portal say the photo is the wrong format?
Most government and visa portals accept only JPG or JPEG. This preset always saves JPG, so a PNG or WebP you add is converted automatically.
