Compress image to 50kb online

Some detail is always lost when a multi-megabyte photo becomes 50 KB, but the tool keeps as much as the limit allows: it scales the photo to at most 1000 px on the long side (the UPSC maximum), lowers JPEG quality from 0.92 but never below 0.5, and shrinks the dimensions further only if quality 0.5 still does not fit. A JPEG that is already safely under the limit is returned untouched. Choose “under 50 KB”, drop the photo and download when the badge is green.

Choose “under 50 KB” and drop the file: the result is always a JPG, saved at the highest JPEG quality that stays under 50 KB, with PNG, WebP and HEIC converted on the way. The size badge turns green before you download; if quality alone cannot reach the limit, the tool also reduces the pixel size, keeping the proportions.

Pick “Photo 20–50 KB — IBPS and bank exams”: the tool lands the JPG inside that window and shows the size before you download, and an amber note warns if a tiny file cannot reach 20 KB. IBPS prefers 200 × 230 px for the photo; for the signature use “Signature 10–20 KB”.

Choose “under 100 KB”, drop the image into the frame and download the JPG. The tool keeps the whole picture, works at up to 1600 px on the long side, lowers JPEG quality before it shrinks anything, and aims for 97,000 bytes, so the file passes whether the portal counts 1,000 or 1,024 bytes per KB. PNG, WebP and HEIC images are converted to JPEG.

Sign in black ink on white paper, photograph or scan it, crop away the empty paper in your phone’s photo editor, then choose “Signature 10–20 KB” and download. That preset aims for 10.5–19.4 KB, inside the 10–20 KB range SSC and IBPS accept; SSC asks for about 6 × 2 cm and IBPS prefers 140 × 60 px. For UPSC the signature must be 20–300 KB and at least 350 px on each side (1000 px at most), so leave white paper above and below it — no more than about 2.8 times as wide as it is tall — and use the UPSC preset.

SSC does not take an uploaded photo: the application captures your photo live with your device’s camera, and a picture of an existing photograph is rejected (SSC CHSL 2026 notice, §9.4–9.5). The only image you upload is the scanned signature — JPEG, 10 to 20 KB, about 6 cm wide and 2 cm high. Choose “Signature 10–20 KB” for it.

IBPS and bank exams: photo 20–50 KB with 200 × 230 px preferred, signature 10–20 KB with 140 × 60 px preferred — use “Photo 20–50 KB” and “Signature 10–20 KB”. UPSC: photo and signature each 20–300 KB and between 350 × 350 and 1000 × 1000 px — use the UPSC preset, which keeps the long side at 1000 px or less and warns when the short side is under 350 px; for a signature, leave enough white paper that it is no more than about 2.8 times as wide as it is tall.

IBPS and UPSC also set a minimum — 20 KB for photos — and reject smaller files. On range presets the tool aims 5 % above the minimum (21,000 bytes for 20 KB), re-encodes at higher quality or a larger size when it can, and shows an amber “below the 20 KB minimum plus a 5 % safety margin” note when even that is not enough, usually because the original is small or very plain. Use the original camera photo or a higher-resolution scan, not a copy saved from a chat app.

For large photos, yes: the tool works at up to 1000 px on the long side for limits up to 50 KB and 1600 px above that, and shrinks further only when quality alone cannot reach the target. The proportions never change, nothing is cropped or enlarged, and the result line shows the final pixel size. A JPEG that already fits the limit with room to spare keeps its original dimensions.

No. The photo is compressed entirely inside your browser. It never leaves your device and nothing is stored.
