Resize Image to 30KB — Free Online Compressor
Compress any image to 30 KB or less. Works with JPG, PNG, WebP and HEIC — the limit regional and sub-national portals set most often.

How to Resize an Image to 30KB
Upload your image
Drop it in or select it — a HEIC straight from an iPhone is fine. At 30 KB expect to cut the dimensions as well as the quality, and the tool does both in the same pass.
Tick "Compress to target file size"
The 30 KB target is already filled in when you arrive from this page, so there is nothing to type. The tool then works upward to the best quality that still fits inside 30 KB.
Download your 30 KB image
Click Resize and save the file. It will be at or below 30 KB, and you will get a warning instead of an oversized file if the target is out of reach.

Where Do You Need a 30KB Image?
30 KB is characteristically a *regional* limit rather than a national one. Sub-national authorities set their own ceilings, and they tend to be tighter than the national systems above them:
- State Public Service Commissions (India) unverified — Maharashtra's MPSC, Karnataka's KPSC, Andhra Pradesh's APPSC and Telangana's TSPSC are reported to cap the candidate photograph around 30 KB in JPEG for their state civil services and Group exams. Each commission publishes its own notification and they do not move together, so check the one you are applying to.
- Provincial and Municipal Portals — City, county and provincial services — permit applications, local licensing, municipal employment — are built and budgeted separately from national systems, so their limits are set independently and rarely raised.
- Admit Cards and Hall Tickets — Where a photo is reprinted onto an entry document, the stored file only needs to survive being printed at thumbnail size, so the ceiling reflects the print size rather than the screen.
- Legacy Government Systems — District recruitment sites, transport department forms and older benefit portals often carry upload limits chosen a decade or more ago against very different infrastructure assumptions.
- Low-Bandwidth Public Services — Services designed to remain usable on a slow or metered mobile connection cap uploads deliberately — a tight limit is an accessibility decision as much as a storage one.
The State Public Service Commissions (India) figure above is marked unverified: widely repeated, but not confirmed on the issuing portal's own page. Portals revise their limits without notice, so confirm the 30 KB figure on the official page for your own form before you submit.
Tips for the Best Quality at 30KB
- Use JPEG — it is the only realistic choice for photographs at this size.
- Set the dimensions to around 200×250px or 250×300px for a passport-style photo.
- Crop tightly around your face and shoulders to remove excess background.
- A plain, light background compresses much more efficiently than a busy one.
- A good starting point for this size is around 250×300px.
Frequently Asked Questions
How do I resize a photo to 30KB for a state exam portal?
Upload the photograph, set the dimensions to about 250×300px, tick "Compress to target file size", enter 30 and keep JPEG selected. That fits any portal stating a flat 30 KB ceiling, which is where the MPSC, KPSC, APPSC and TSPSC forms usually sit — though each commission sets its own figure per notification, so check yours before you upload.
My portal lists a size in bytes, not KB. How do I convert?
Divide the byte figure by 1,024. A 30,720-byte limit is 30 KB, and 51,200 bytes is 50 KB. Enter the KB figure in the target size field. Some portals divide by 1,000 instead, which makes their stated "30 KB" very slightly smaller — targeting the KB figure directly stays safe either way.
Is 30KB enough for a clear passport-size photo?
Yes at typical portal dimensions. At 250×300px a 30 KB JPEG keeps facial features clearly distinguishable, which is what a verification check needs. It is not enough for a photo that will also be printed at full size — keep your original for that.
The portal rejected my photo even though it is under 30KB. Why?
Almost always a dimension or format problem rather than a size one. Check the exact pixel dimensions the portal asks for and confirm it wants JPEG — plenty of portals reject PNG outright regardless of file size. A handful also enforce a *minimum* size, in which case compressing harder makes the rejection more likely, not less; tick "Also keep it above a minimum size" in the tool if your form states a floor.
Which format gives the smallest file at 30 KB?
JPEG, and at 30 KB the choice matters more than it does at any larger target. PNG is lossless, so it ignores a 30 KB instruction completely — a PNG export comes out whatever size the image dictates, which at this tier is many times over. WebP would be smaller again, but most government forms asking for 30 KB name JPEG explicitly, so use JPEG unless yours says otherwise.
Will the image still look acceptable at 30 KB?
Only if you bring the dimensions down to about 400×400 pixels along with it. That is roughly what 30 KB carries at decent quality; asked to cover a full 12-megapixel photo, the same 30 KB shows visible blocking around edges and in skin tones. Shrink the pixels first so the budget covers fewer of them, and convert to grayscale if your form permits it — that alone frees a useful share of 30 KB.
Can I upload a HEIC photo from my iPhone and get 30 KB out?
Yes — HEIC, JPG, PNG, WebP, BMP, TIFF, GIF, AVIF and SVG all work as inputs, so an iPhone photo goes straight to a 30 KB JPEG with no separate conversion step. That matters here because an untouched HEIC is usually a few megabytes, roughly 100× over 30 KB. Save as JPEG for the 30 KB target; PDF, PNG, WebP, BMP and TIFF are available too, but PNG cannot be compressed to a size.
Are my images uploaded anywhere?
No. The compression to 30 KB happens in your browser through the Canvas API, so the photo never leaves your device — nothing is sent to a server and nothing is stored. Open your network tab while the 30 KB target is applied and you will see no upload request at all. Squeezing a phone photo roughly 100× down to 30 KB is exactly the kind of job people hand to an unknown upload site while filing a form on a patchy portal connection; here the 100× reduction happens on your own machine, which is why it still works when the connection drops out mid-form and why it is safe for an identity document.
