Image compression
Visa portals, government forms, and older job boards often reject anything over 100 KB. A phone photo is usually 2–5 MB, so you need a real cut — not a slider guess. Set 100 KB as the target, download a file that actually fits, and keep the work on your device.
Open the Image CompressorVisa portals, government forms, and older job boards often reject anything over 100 KB. A phone photo is usually 2–5 MB, so you need a real cut — not a slider guess. Set 100 KB as the target, download a file that actually fits, and keep the work on your device.
100 KB is a file-weight cap (~102,400 bytes), not a width and height. A visa or exam upload that says “max 100 KB” will reject a 101 KB JPEG even if the pixels look right. Check Finder or Explorer after you download. Portals that round “0.1 MB” upward will also bounce a file sitting on 100.0 KB — aim for 95–99 KB.
That ceiling is common on government and visa forms, exam registrations, HR systems on slow office networks, and email workflows that still treat a single attachment as expensive. It is stricter than a 500 KB website image or a 1 MB share, and looser than a 50 KB Passport Seva-style ID crop. Use the number printed on the form, not a smaller target “just in case.” Crushing to 20 KB smears a face a reviewer still has to read.
Target-size mode in the Image Compressor searches for the highest JPEG (or WebP) quality that still fits, and only shrinks resolution if quality alone cannot get there. Stay on JPEG unless the field lists WebP. A photograph saved as PNG is why “reduce image size below 100 KB” often fails — convert to JPEG first, then run the 100 KB target again.
For passport and ID photos, crop to the official millimetres first, then compress. A US 2×2 or India 35×45 mm frame that happens to be 80 KB still fails if the geometry is wrong. The longer walkthrough is How to reduce image size under 100 KB. Need more headroom for a site or portfolio? See Compress image to 500 KB or Compress image to 1 MB. Prefer WebP for a modern CMS? Use Compress to WebP. Nothing is uploaded.
Open Tokitool’s Image Compressor from this page, switch to target size, set 100 KB, and download when After is under 100 KB. That is the same job as “reduce photo to 100kb” — you are changing file weight, not inventing a new pixel size.
If After is still over, the picture has too many pixels or it is a PNG photo. Convert to JPEG, crop tighter, or start from a smaller export, then set 100 KB again. Aim a little under (95–99 KB) so a portal that rounds “0.1 MB” does not bounce you.
Crop to the form frame first (or a modest headshot), then let target mode pick quality. A giant canvas crushed to 100 KB looks worse than a form-sized JPEG at 60–75% quality. Open the download at 100% zoom before you submit.
Use the 100 KB target, then check Finder or Explorer — not the camera-app “dimensions” line. Upload the new download. If the field also lists millimetres or pixels, resize those first in the Passport Photo Resizer, then come back here.
Compression stays on your device, so a weak uplink does not matter until you upload the small file to the government or visa portal. Get under 100 KB here first; the form upload is then a short transfer.
No. The Image Compressor uses the same in-browser Canvas path as the 500 KB and 1 MB landings. The file never leaves your device.
