When a picture genuinely cannot fit the kilobyte limit at the dimensions you asked for, the result now says so and tells you how much it came out at, instead of handing you a file that a strict upload form would turn away.

Asking for something enormous used to be accepted, thought about for half a minute, and answered with a broken file. Anything past roughly fifty megapixels is now declined the moment you type it, with the reason.

Changing the unit converts what you entered rather than reading the same number in the new unit. 800 × 600 pixels becomes 6.77 × 5.08 cm, not a request 118 times larger.

Empty, zero and negative sizes used to quietly become 100 pixels and produce a real image at a size nobody had asked for. Each is now pointed out by name, and the button waits until it is fixed.

Starting a large resize, then pressing New image or editing the size, no longer lets the abandoned job finish quietly and put its own answer on screen. What you see always belongs to the settings currently in the boxes.

Each preset now describes exactly what it produces, choosing one without a size limit clears the previous limit, and the DPI and target-size boxes announce their own names.

HEIC photos are converted using your browser's own decoder, which Safari and iOS provide. On browsers without it, the tool now tells you within a fraction of a second and points you to the quickest way forward, rather than leaving you waiting on a conversion that cannot finish.

When you ask for 20 KB, the file you download is under 20 KB. If the picture cannot fit at its current size, the tool reduces the dimensions until it does instead of handing you something a strict upload form would reject.

Compression now uses far more of the size you allow it. Where a 13 KB limit once produced a needlessly small file, it now fills the budget — and tightening a limit by one kilobyte costs about one kilobyte of quality, not five.

If your photo is already under the target, you get the original back byte for byte. Re-encoding something that already fits only costs quality, so the tool no longer does it.

An animated GIF or WebP that already meets your target is returned exactly as it is, with every frame intact. Where an animation genuinely has to be re-encoded to fit, you are told before it happens.

A photo that was cut short during download or transfer still opens in a browser, with the missing part rendered blank. Every format is now checked for completeness on selection, so you find out immediately instead of discovering it after uploading.

Cancelling a large compression stops it within about a second and returns the controls straight away. A cancelled job can no longer finish quietly in the background and replace what you are working on.

The Form Photo Checker reads the way real upload pages are written: "no higher than 1200 × 1600", "neither below 20 KB nor above 50 KB", "at least 600 × 800 but never above 1200 × 1600", "20 KB ≤ size ≤ 50 KB", and format rules such as "all formats except WebP".

Where a requirement contains a number the tool cannot read with certainty, it leaves the field empty and explains why. A blank field gets filled in by hand; a confidently wrong one does not.

Converting a transparent image to JPG tells you the see-through areas became white. A target too small for a usable picture says so. A result that grew rather than shrank is labelled as such instead of being reported as a saving.

The upload area, size presets and parser notes now work properly with keyboard navigation and screen readers, and very long filenames no longer stretch the page sideways.

Images far beyond what a browser can hold in memory are refused as soon as they are chosen, using the size recorded in the file itself, so a tab cannot be brought down by one.

Create invoices, quotes and receipts as PDFs entirely in your browser, with VAT and tax handling, multiple currencies, your own logo, and commission-based billing for freight and agency work.

Convert .docx files to PDF locally, keeping headings, lists, tables and images, with no upload step.

Merge, split, rotate and delete pages in a PDF without sending the document anywhere.

Redacted areas are rebuilt so the removed content is genuinely gone from the file rather than merely hidden behind a box.

Step-by-step pages for the requirements people actually face — exact kilobyte caps, fixed pixel sizes, passport and visa portals, and government forms.
