Formats in & out
In: JPG, PNG, WebP, GIF, AVIF, HEIC/HEIF. Out: WebP (smallest), JPEG, PNG, or ICO for favicons.
The process
From a raw file to a size-capped image
The whole pipeline, in the order you'll actually use it.
Upload
Drop images onto the drop zone, click to browse, or paste from your clipboard with Ctrl/Cmd + V.
Crop (optional)
For a single image, trim the edges or lock to a 1:1, 16:9, 4:3, or 3:4 aspect ratio before compression.
Configure
Set a target width, a maximum file size in KB or MB, an output format, and optionally a fixed quality.
Preview
For single images, drag the quality slider to compare the original against the compressed output live.
Convert
Click “Convert & Download All” to process and save. Files are named [name]-compressed.[ext].
The core idea
Compress to a target file size
Most converters let you pick a format and hope. Sukat takes a hard ceiling — say, 200 KB — and binary-searches for the highest quality that fits underneath it. If even quality 1 is too large, it reduces dimensions as a last resort, so you always get a file that meets your limit.
Use Auto mode (quality 0) to optimise automatically, or drag the slider to a fixed 1–100 for manual control. In manual mode, if the chosen quality overshoots your target, the download button disables until you lower quality or raise the ceiling.
Reference
Common file size targets
Different platforms and forms enforce different caps. Set yours in KB or MB and Sukat lands underneath it.
20 KBUPSC, SSC, and IBPS signature uploads 50 KBOlder recruitment portals, ID badges, low-bandwidth thumbnails 100 KBLinkedIn, X/Twitter, blog thumbnails, job portals 240–500 KBPassport photos for US, Schengen, Canada, India portals

Capabilities
Everything that runs alongside
All of it local. Nothing here ever uploads a file.
HEIC & iPhone photos
Drop iPhone HEIC files, pick JPG or PNG, get a universally compatible image. Whole camera rolls, no uploads.
Quality slider
Auto (0) finds the best quality under your cap; 1–100 for manual control with a live preview.
Crop before compress
Preset ratios, arrow-key nudges, native-resolution cropping. PNG keeps transparency; JPEG otherwise.
Remove background
A client-side AI model (~40 MB, cached after first use) isolates the subject into a transparent PNG. Revertible.
Batch & ZIP
Queue many files; batch uses Auto quality per file. Bundle everything into one timestamped ZIP.
Works offline
Once loaded, compression, resizing, HEIC decoding, and ZIP packaging keep working with no connection.
Why WebP
Typically 25–35% smaller than equivalent JPEG with no visible loss. Supported in every modern browser.
Predictable naming
photo.png becomes photo-compressed.webp. The source clears after download so you start fresh.
