Get your passport-size photo under 50 KB with the best quality that fits. The target is preset and the photo never leaves your device.
“Photo size should be between 20 KB and 50 KB” is one of the most common lines on online application forms: entrance exams, government job portals, scholarship sites, bank forms and passport or visa applications. A photo straight from your phone is usually 2 to 5 MB, so it is rejected. This page lets you compress image to 50KB online in one step, with the target already chosen. It is a 50KB image compressor built for passport-size and ID photos: it keeps as much detail in the face as the size allows, and it does all the work inside your browser, so your photo is not uploaded anywhere. On this page you will find how it chooses quality and pixels, real numbers from our own test, a size chart for passport photos in centimetres and pixels, a comparison of JPG and WebP at 50 KB, and what to type when a form gives a range like 50 KB to 150 KB.
Think of 50 KB as a budget that can be spent on two things: pixels (how big the picture is) and quality (how much detail each pixel keeps). The tool always tries to spend it on quality first. It saves your photo at 92% quality; if that is over 50,000 bytes it saves it at 50%; if 50% fits, it searches between the two for the highest quality that still fits. Only when even 50% is too big does it reduce the width and height, by the amount the size overshoot suggests, and searches again. For big photos it first guesses a starting size from a small preview, which saves time on phones.
Worked example (measured). Our 2000×3000 test photo of 672.9 KB came out at 49.8 KB, 633×950 pixels, quality 61% as JPG. With WebP chosen under More options, the same photo gave 49.4 KB, 718×1076 pixels, quality 78%. Both are under 50 KB; WebP simply packs more picture into the same budget.
Drop, choose or paste your photo into the box. The 50 KB button is already selected, so you don’t need to set anything.
The row shows the new size, the pixel size and the quality, for example 49.8 KB · 633×950 · quality 61%. Look at the thumbnail to check the face.
Click Download to get a file like photo-50kb.jpg. With several photos, Download all (ZIP) saves them together.
50 KB keeps roughly 400-600 pixels of width on a phone photo, enough for a clear face on an admit card or ID.
Quality is searched between 50% and 92%, and the best value under 50 KB is kept. Pixels are trimmed only when quality alone can’t reach it.
JPG is the default for forms. WebP, under More options, kept 28% more pixels at the same 50 KB in our test.
Add up to 30 photos. Each one is compressed separately and nothing is uploaded, signed up for or watermarked.
A passport-size photo is printed or shown small, so 50 KB is usually plenty. Forms often give the size in centimetres or inches instead of pixels. At 300 DPI, the usual print resolution, these are the pixel sizes (computed: millimetres ÷ 25.4 × 300):
| Photo size on the form | Pixels at 300 DPI | Fits in 50 KB? |
|---|---|---|
| 3.5 × 4.5 cm (35 × 45 mm) | about 413 × 531 | Yes, usually at high quality |
| 2 × 2 inch (51 × 51 mm) | 600 × 600 | Usually yes |
| Full phone photo (e.g. 3000 × 4000) | no change | Pixels are reduced to fit |
To get an exact size like 413×531, open the image resizer, choose Resize by “Exact size” and “Fill and crop”, which fills the frame and trims the edges evenly from the centre. Then drop the result here. If it is already a JPG under 50 KB, the tool says “already under the target, kept as it is” and leaves it untouched.
Both formats are lossy, but WebP is newer and usually smaller than JPG for the same look. In our test it kept noticeably more pixels inside the same 50 KB:
The catch is acceptance. Most exam, government and passport portals list only JPG or JPEG, and some reject WebP. So for forms keep JPG, the default. WebP is a good choice for your own website or when a site clearly lists it. To switch, open More options under the size buttons and choose WebP.
The file you download is a real JPG with the .jpg ending, for example photo-50kb.jpg. That works on forms that say “JPG”, “JPEG” or “.jpeg”, because they are the same format. If you add a PNG, HEIC or WebP photo, it is saved as JPG too. Transparent parts of a PNG, such as a cut-out background, turn white in JPG, which is what most photo forms want anyway.
People search for a “50 KB PNG”, but PNG is lossless: it has no quality setting to lower, so a photo as PNG is usually far bigger than 50 KB. This tool therefore saves JPG or WebP only. If a form truly demands PNG under 50 KB, first make the photo small in pixels with the image resizer (choose PNG as output there) and check the size; a small, simple image can fit, a detailed photo often won’t. For a PNG you already have, PNG to JPG changes only the format.
When a form gives a range, the upper number is the one to type. The tool lands just under it for normal photos. Use this as a quick guide:
| The form says | What to do here | Watch out for |
|---|---|---|
| 20 KB to 50 KB | Keep the 50 KB button | Nothing; normal photos land near 50 KB |
| Max 30 KB or 40 KB | Type 30 or 40 in Target size | Face gets a little smaller in pixels |
| 50 KB to 100 KB | Press the 100 KB button | A JPG already under 50 KB is kept as it is, so it stays below the minimum |
| 50 KB to 150 KB | Type 150 in Target size | Same as above: start from the original camera photo |
The tool never makes a file bigger to reach a minimum. If your result is below the lower end, the photo you started with was already too small, often a copy that came through a chat app. Use the original from your camera roll.
Some forms limit pixels too, like “maximum 250 pixels wide” or “200×230 pixels”. Set the pixels first with the image resizer: Resize by “Width” for a width limit, or “Exact size” for both sides. A 250-pixel-wide JPG is small; it is very often already under 50 KB, and this page will then keep it as it is instead of saving it again.
There is no single “50 KB PDF” button, but two steps do it. Compress the photo here, then open JPG to PDF, add the photo, choose PDF size “Smaller file” and press Make PDF. Keep the output as JPG, not WebP. A JPG made here has no rotation data and its longest side (950 px for our test photo) fits the Smaller file limit of 1600 px, so JPG to PDF puts it into the PDF byte for byte instead of saving it again. The PDF is about the size of the photo plus roughly 1 KB per page; in our test a 107.8 KB JPG became a 108.8 KB PDF. So for a 50 KB PDF, type 48 in Target size, then make the PDF and read the size it shows.
In every case we measured, the result was under 50 KB: 49.8 KB as JPG and 49.4 KB as WebP from our photo, and 49.9 KB when we compressed a 70.2 KB, 1200×800 WebP to 50 KB as WebP. The limit is checked against the real byte count, with 1 KB counted as 1000 bytes, which is the stricter of the two readings. A few honest notes:
Most 50 KB compressors either let you set a quality and hope, or upload the photo and send back a file at one fixed setting. This page treats 50 KB as a hard limit and finds the best quality inside it for each photo separately, by saving real test files in your browser and weighing each one in bytes. A busy photo and a simple one get different settings, because they need different settings. The result row tells you exactly what was used, so you are never guessing.
Nothing is uploaded. That matters for ID photos, which are personal data you would not hand out on a website you don’t know. The work runs on your phone or computer, works after the page has loaded even without internet, and the downloaded JPG is a fresh file with no camera details or GPS location inside. Copy summary copies the before and after numbers for every photo, which is handy when you prepare photos for several family members at once.
We measure each photo’s width and height after turning it upright, its original file size, and the exact size of every test file the quality search produces. We show the final size, pixel size and quality. We do not measure face position, background colour, sharpness or whether the photo meets passport rules, and the compressor does not crop or set exact pixels; the resizer does that. We only re-save what is needed: a file already under the target in the same format is kept as it is.

| Batch | Up to 30 photos, ZIP download | Sometimes limited on free plans |
| Watermark or sign-up | Neither | Sometimes |
| Works offline after loading | Yes | No |
Signature box on the same form? Use compress image to 20KB. Form allows more? A 100 KB photo looks sharper.
Always check the form’s own instructions for photo size, pixel size and background colour.
Drop your photo into the box on this page. The 50 KB target is already set, so the compressed JPG appears in a second and you click Download.
JPEG and JPG are the same format, and JPG is the default output here. Drop the JPEG in, and the file you download is a JPEG under 50 KB.
Compress the photo here first, then make the PDF with the JPG to PDF tool and the Smaller file option. Keep the output as JPG: a compressed JPG goes into the PDF unchanged, so the PDF is about the photo size plus roughly 1 KB per page.
You can drop a PNG in, but the result is a JPG or WebP. PNG is a lossless format, so it can’t be squeezed to a set size the same way, and most forms that ask for 50 KB accept JPG.
First set the pixel size with the image resizer (Resize by Width or Exact size), then drop that file here. A photo that small is often already under 50 KB and is kept as it is.
Yes. Type 30 or 40 in the Target size box. The tool then works the same way and keeps the best quality under that number.
Some detail is always lost, but you can keep it hard to see: start from the original camera photo, crop to head and shoulders, and use a plain background. Those leave more of the 50 KB for the face.
Yes. It is free, has no sign-up and no watermark, and works in any current browser on phones and computers.
